I agree with the tweet the OP saw. It’s very easy to make hot dogs very consistent, so at mediocre quality levels, the hot dog is still pretty decent. Burgers have a lot more variability: The best ones are better than hot dogs, while the worst ones are worse than hot dogs.
I’d pay $25 for a really good hamburger; I’d never pay that much for a hot dog. OTOH, If I’m hungry, I would happily eat a hot dog from a random cart in the street, but I’d never eat a McDonald’s (or Burger King et al) hamburger. So I guess I agree with the OP’s proposition.
Unless it was a really bad burger - worse than a 5/10 - I’d go for the burger. I just never really liked hot dogs. I don’t think they’re bad, but they just don’t taste that good to me.
I think so, yeah.
I think of hot dogs as “kid food”—which doesn’t mean I won’t eat them occasionally, or that I don’t think other adults do or should. They’re cheap (at least the cheap ones are), easy to make (since they come pre-cooked, they’re relatively foolproof), and they’re a blander version of their more grown-up cousins like bratwurst and smoked sausage.
How about the bun? There have been times in my life where I’ve been told - sorry we don’t have any hot dog buns but you can put it in a piece of bread. NO NO NO!! The same with a hamburger. If a nice soft bun isn’t available, I don’t want it.
Hot dogs don’t vary much in quality. A really nice one is great and all but hot dogs are processed meat and there’s only so much you can do to alter the taste.
Hamburgers, on the other hand, range from pre-frozen thawed out patties that taste like sawdust to homemade, fresh patties that are full of flavor.
Oh dear, yes they do. The difference between a Bar-S and a natural casing Vienna Beef or Sahlen’s is orders of magnitude. Then again, I’m very picky about my dogs.
If you are, you’d never let them eat Bar-S! 
I’m struggling to think of a situation in which I’d chose a hot dog over a burger, but then again, I don’t eat at McDonalds. However if you’re willing to consider a sausage wrap as a hot dog equivalent, you’ve got me in a quandary.
For me personally, there’s no contest here. I’d prefer a 5/10 burger to a 10/10 hot dog.
I interpret 5/10 as if you took every single hot dog made in America and you personally ranked them from most delicious to least delicious, the 5/10 ones are the ones from 45%ile to 55%ile in deliciousness.
Part of the reason I think the OP’s statement is true is because of our definitions of hot dogs and burgers. If you had a foie gras stuffed wagyu patty with truffle shavings, on a brioche bun, that’s still a “burger”, but “hot dogs” quickly become “bratwursts” and “sausage sandwiches” and other more specific things as they move up the quality spectrum. There are some dishes of ground meat in a long bun that I would rate superior to a burger, like a meatball sub, but they’re no longer hot dogs.
I had a hotdog made by a butcher and cooked by a chef friend at a food/beer pairing. The hotdog was amazing.
I’m OK with your definition of 5/10 but I think you’re carrying the rest too far. Not every chopped substance formed into a patty is a burger, and not everything resembling a sausage is a dog. I think this particular discussion should focus on more commonly used definitions of ‘burger’ and ‘dog’.
Today is NATIONAL CHEESEBURGER DAY!! Get off your butt and support your country in this time of national crisis. 
I wish I’d known that before I got pizza for lunch.
I sympathize; tell you what: when National Pizza Day rolls around, we’re going out for burgers. Big burgers. Juicy burgers. Grilled to perfection burgers. Doing our country proud.
Yeah, a good burger is a true delight.
I like hamburgers at both extremes of the spectrum. I make big, thick, rare sous vide burgers from ground steak. Mmmmmmm.
But I also love the smashburgers made at Krave, a tiny restaurant in Phillipsburg, Sint Maarten.
If I was limited to buying either a hamburger or a hotdog at a convenience store, I’d certainly buy a roller hotdog over the paper-wrapped and microwaveable hamburger. In fact, just this week I made a stop at the Circle K to buy an all-beef hotdog, because I didn’t want to buy a whole package of them (and the buns) at the grocery store, knowing we’d get sick of them at home before finishing them all. If they’re advertised as Chicago-style or all-beef, the hotdog will certainly be good.
