I ride a Specialized S-works Enduro as my primary bike, around here it would be considered a half decent “trail bike”, with about 130mm of travel in the front and rear. It doesn’t have enough travel to be considered a free ride bike and its way to heavy and not laid out like a serious XC bike. I started riding when suspension started to go mainstream and was met with quite a bit of resistance, anyone remember the Girvin stem suspension? So after watching years of mtb suspension evolution here’s my take/advice.
A full suspension is definitely worth the money. Depending on how serious you are about the sport, one of the major factors that will keep you on or off your bike is comfort. If your a die-hard XC weight weenie who is willing to sacrifice quite a bit of comfort for the sake of shedding some weight and pedaling efficiency in order to win races or impress your friends with your low cadence and heart rate then maybe a hardtail is for you. If your anyone else from a novice to a weekend warrior the comfort and ability you gain on a full suspension far outweighs the drawbacks of reduced pedaling efficiency and added weight.
While climbing a full suspension bike allows your wheels to track better along the bumpy terrain, keeping the wheels in contact with the ground while maintaining traction. The rear wheel of hardtail has more of a tendency to chatter or get bumped around during climbs causing you to lose traction or to rise/hover over your saddle to absorb the bumps in your legs and not directly on your butt while seated. Having a full suspension will help you conquer much ruttier gnarlier terrain on the flats and downhill, anything that reduces the amount of punishment that you take while holding on, helps you maintain your balance and keep the bike stable and upright.

As for rear suspension, it’s your choice. I wouldn’t recommend it. The only time you really need rear suspension is if your are doing 5’+ drops. For regular trails, your legs work far better as suspension. Not only is there the added weight and expense, but you lose efficiency. Some of the power you put into the pedals will be absorbed by the suspension. Try a long steep climb on a fully suspended bike and on a hardtail and you’ll see what I mean.

Saying that you only need rear suspension for 5’ drops is like saying you only need suspension on your car for huge potholes and speed bumps. Not only will most people never see a 5’ drop on their bike but many full suspension bikes aren’t designed to take 5’ drops. The Specialized Epic is a full suspension bike that is not in any way meant to be taken off 5’ drops. In fact that bike is pretty much designed to be as efficient and glued to the ground as possible. You seem to be concerned with efficiency yet you say your legs work far better as suspension than a frame? In order for your legs to absorb impact, most of your weight has to be supported by your legs in order to cushion the blow which is very energy inefficient. I prefer to stay seated as much as possible with all of my weight on my seat allowing my legs to focus on pedaling while my suspension soaks up the bumps. Which do you think is easier, just sitting on your seat for an hour, or hovering over your seat for an hour while your legs hold you up. In order for your legs to act as suspension you would have to be doing the latter of the two. Plain and simple, suspension helps you stay seated more which takes extra strain off of your legs.
All that being said, yes you do lose some efficiency in the movement of the suspension, many companies have designs that are supposed to isolate pedaling forces from suspension bob along with shocks that help cancel out pedal induced bob. I use a front and rear lockout and have never had any problems

On lockouts for the rear suspension, what the guys at the bike shop told me (and they sell plenty of high-end full suspension bikes) is that it’s not really the same as a hardtail. A locked rear shock absorber won’t take the same kind of pounding that a hardtail will; you run the risk of blowing out the seals at some point. I imagine this is more of an issue if you ride that way a lot.

A locked rear shock isn’t meant to take the same kind of pounding a hardtail is. It’s not supposed to take much of a pounding at all, that is why you have locked out your rear suspension, in order to tackle a section where the impact on your bike will be low and the pedal induced bob needs to be low. The parking post in your car wont take much of a pounding if you keep putting it in park while your moving fast. Use the lockout and the “P” icon on your car when they are meant to be used and they will last a while.
Disc brakes: get hydraulic, Hayes Shimano and Avid are all good brands for a decent price.
I personally don’t like the Giant suspension design, but that doesn’t mean it isn’t a top notch bike. My friend just bought a Giant Trance with the maestro linkage and hydraulic disc for about 1700 out the door. It was a year old and on sale. Just to give you an example of what you can get.
Go to your local trail head and talk to the guys on full suspension bikes, ask them what they think, and ask them if they would ever go back to a hardtail.
