Wow, I didn't know there were that many burger chains in the USA. We only have burgerking and macdonalds, that's it. Out of those two I definitely prefer burgerking as being the far superior choice over mcdonalds.

We have some local chains too that try to do burgers, however I don't get a burger often, so I can't comment on that. I only know that I once tried a burger from our local chain Smullers and it was absolutely terrible.

Of course there are also restaurants that sell actual house made burgers, but imo that's a completely different category/class.
