Serious Cheeseburger or BigMac ?

It depends what type of Cheeseburger.

If it's a crap Cheeseburger then I would go for a Big Mac.

But if it's a really good Cheeseburger then I would go for that instead of a Big Mac.

Because in my place there is a really good American style burger restaurant and I go there once in a while and eat a nice Cheeseburger or Hamburger.
