Invisibility, hands down. I would use it to fight crime in that I would steal stuff so I wouldn’t have to work anymore.
Oh wait. That’s not fighting crime, is it? What I meant was, I’d be a criminal.
flight, no doubt about it.
i love skydiving, and nothing is as exhilarating as that. I’d love to be able to fly (maybe so cos i’ve no drivers licence and need to cycle everywhere 
)
invisibility would come in handy if you need to spy on things/people, but i don’t feel an urge to do so. Plus I’d find it disturbing to be “looked through”…
brrr.
Invisibilty all the way.
I wouldn’t need to travel very far if I were invisible.
Somehow, and as hard as this might be to imagine, I suspect that spying in the women’s locker rooms would get boring after an hour or so.
But I’d still pick invisibility. Mostly because people are always bugging me for something!
“Hey, do you know where Christian is?”
“Nope, haven’t seen him.”
“Hey, did you just hear a chuckle?”
That’s a bit far-fetched
Boring? NEVER!
Returning to the OP for a moment, I thought of a condition that should be added under “invisibility.”
6. Despite the fact that your retinas are invisible and no longer trap light, you are still somehow able to see.
'Cause of course being an invisible blind dude would just suck.
Flight all the way. It’s just fun! I know that because of my once-every-two-years flight dreams.
And I’d wear a goofy bird costume to throw off radar, although I do wonder whether radar would even pick up on a shrimpy little guy like me.
Occasionally, of course, I’d wear a Superman costume. Make folks happy.
Invisibility just doesn’t sound like much fun to me.

Has to be flight! Invisibility may be good for spying on people or robbing a bank but better than flight? No way! Besides why rob a bank? I’d go to Hollywood and be the stunt double for a Superman or similar movie. Paying me a few million for the work would certainly be cheaper than paying 100 million for special effects. So no need to rob a bank. And think of all the places you could go! Could being invisible get you the top of Mt Everest? How about flying around the Grand Canyon? Invisibilty? Pffftth!
Invisibility - and soon after getting the power, I’d become the most ruthless vigilante the world has seen. I’d beat men who beat thier wives, punnish bosses who abuse their power, and kill the Hitler types in our world today. No one could escape me, and I would not stop till satisfied. I’d start with that camel fucker in Iraq.
wow I’m in a mood today.
Well, never having had that sort of opportunity, I can’t say for certain, of course. I was thinking of comments made by people who have frequented naturist camps/beaches/etc., about how the lack of clothing quickly ceases to catch your attention. But I haven’t gone to such an place or event, so I don’t really know that, either.
Of course, it depends on exactly what actually goes on in women’s locker rooms, too. “C’mon, it’s just a locker room. I’m sure that they do just the things that we do.” (Through the vent, women’s voices: ) “Oh, my breasts have just been so dry and chapped lately. Would you rub this lotion into them, please?” “Sure!” :eek: (by vague memory, from Not Another Teen Movie)
That’s not to say that voyeurism wouldn’t be a temptation if I had that power; I’m just thinking that, if that’s someone’s only reason for wanting it, they might want to think a little harder. You wouldn’t want to spend the rest of your life saying, “Dang! If only I’d picked the flying!”
Phlosphr has got it right, though-this would be a damn fine crimefighting power. Flying is of very little use from a social utility point of view, but an Invisible Person could really screw with organized crime, etc. Or with law-abiding citizens, of course, but he and I would never use our powers that way. Mostly.
I choose flight. I may be a perv but why watch women get naked when they would gleefully join you for the Mile High club?
1000 MPH? Heck, LA to NY or Hawaii in 2 1/2 hours? All I have to worry about is the FAA giving me citations for sonic boom noise violations. Do I have to file a flight plan? Can I outmanuver a SAM? Will my flight envelop protect me from 90 degree turns at mach 1.2?
How can invisibility help firemen or rescue workers? I can get into any sports event as the half time show. I can fly to vegas in under 20 minutes. I can shoot down most fighter aircraft with a rifle. I would be nearly invisible to radar if I carry a radar reflective wedge. I wouldnt have to worry about crashing in a plane. I will never need a car or gasoline. Commuting in traffic is a memory. Plus I can wear some garishly colored skin tight leotards!
Depending on the level of Invisibility you might still be “seen” in infrared. Also, once people knew you could become invisible how long do you think the whitehouse will take to install pressure sensors?
Still, if you could take a gun and it became invisible with you, you’ll be quite powerful. You wouldn’t even have to been all that close to the target, and once you assassinated someone, you’d be long gone and invisible.
I choose invisible. I would do my part to fight crime, but a as superpower it’s not much. You’d get a few good punches in if you attacked someone but after they get a hold of you, your power is mostly taken.
Flight. Both options open up some cool possibilities, but basically I just want to FLY.
I’d have to pick flight. Why? Because if you are invisible, that means light passes through you, which means you are blind. Vision works by having light interact with your retinas. If light passes through your retinas, no vision, hence you are blind. What fun is being invisible when you can’t see what other people are doing when they can’t see you?
I thought this would be addressed in the OP, but it wasn’t. Not surprising though, I don’t think any tv show or movie has ever treated this realistically.
If I could be invisible and still be able to see, then I might go for it.
Flight.
Most of the applications of invisibility are immoral (IMHO) since I’m not going to spy on criminals or America’s enemies. I’m also not that much of a voyeur, and I’d get pretty jaded with sneaking into locker/bedrooms pretty fast (guilt at invading privacy aside).
Flight, OTOH, has a host of applications that aren’t immoral and won’t become boring. From reaching things on high shelves to flying across campus to cheap vacations, there’s tons of things I can do.
While both flight and invisibility have huge military/espionage potential, I think the government, once they figure out how I fly, will be more likely to leave me alone and not send me on suicide missions.
Can you explain how “realistic” invisibility would work, or for that matter, “realistic” flying ? 
Oooh, couldn’t I just take them both? I mean, you’d just end up moping continually that you didn’t take the other power.
If forced to choose, invisibility. I’m not that much of a heights person.
Right now, being 4,500 miles from my fiancee, I’m tempted to take flight…but if I couldn’t switch powers, I’d probably take invisibility. (I’ll be married in 4 months anyway, so the need for flight is only 4 months long).
I’d really like to have invisibility + one other trait: The ability to make yourself not have physical properties while invisible. The only thing that works like that is your feet…so that you won’t fall through floors and the like. But that way, if some car hits you, nothing happens…if someone shoots in ‘thin air’ you can’t be hit by a stray bullet. You can walk through walls. Kick ASS.
I’d probably use it for good most of the time…you know, averting wars, etc. Think of what you could do! Plus, I just think it would be so much fun to see what people are really like behind closed doors. And, the hot women…what they’re really like behind closed doors. Of course, my lady might have an issue with that one.
Flight, for sure!
a-fun
b-see your friends and family, with one family member along for the ride, anytime! No more getting frisked by security guards and hassled because your keys have metal in them!
No question.
What is it with all you people who think being invisible means you can go anywhere?
Doors still have locks. Invisibility doesn’t get you into the White House, it gets you on the grounds of the White House. Getting the rest of the way takes a bit more skill, even if you’re invisible.
And as for practicality, well, hey – transportation is one of my major costs. Car, gas, parking, the hours of unpaid commuting time… man, I’d pick flying hands down. I could live anywhere I wanted to; real estate is cheap farther away from the city. There’s no contest; flying is the most useful on a day-to-day basis.
Hell, if you really want to fight crime, the easiest way to do it is to get in fast, smack the criminal around, and get out. Can you imagine the effectiveness of a thousand-mile-per-hour dropkick? I say an invisible man can be shot, but a man travelling at mach 1.3 is a very difficult target. You can pick up criminals and intimidate them at 30000 feet. You can have a Secret Lair in an inaccessible place. You can finally throw out that damned Air Miles card.
If you want to be a criminal, well, go rob the bank in, say, Boise Idaho, then head back to your pad in L.A. for dinner. You think the Boise types are going to look for you in L.A.? Who needs invisibility when you can put on a mask? With flying you can get in the windows and balconeys everyone leaves open because they think they’re inaccessible. Or peek in the bathroom window of the babe who thinks nobody can peek in her bathroom window. You can steal an old lady’s purse and be gone before the do-gooder down the block has a chance to throw a can of soup at you. An invisible man still has to get away.
Flying is the way to go, no question. You invisible people are nuts.
