Lots of great cheeses for cheeseburgers depending upon what you're going for.

cheddar (the classic, huge range of texture and flavor from cheap grocery store brand to aged, crumbly, sharp stuff depending on what you want)
provolone (ok, not tons of flavor usually, I'd want it thick)
swiss (good flavor for certain types of burgers)
blue (TONS of flavor, good for certain types of burgers)
pepper jack (if it's good, then it'll be spicy with some good flavor)

I haven't tried it on a burger, but I've made a grilled cheese with huntsman which is nice as you get a combination of flavor profiles in the same cheese.
