Oh yeah, I love all types of these. But there's also something nice and gooey about American cheese for grilled cheese or a burger (as this was bought for). Also, growing up my mother told me in the middle of sleepless nights that eating a slice of American cheese made you sleepy. In retrospect, it was probably a clever placebo. albeit ironic. I believe casein protein, which is more prevalent in real cheese, actually does do that since it's harder to metabolize.
Swiss cheeses melt very well too.
