Both are good and have their place. I'd probably do a smash burger if I was going for like a more classic kind of burger flavor but I'd probably do a thick burger if I was to try to, I don't know, make something fancy or do like an interesting stack.

Depends if there's ice cream and cheese curds

I like all burgers. Smash burgers and Oklahoma onion burgers are favorites.

Smash. Faster and easier to cook, easier to stack.

Win/win
