Out of the options in the images posted, I'm picking salty. In general though, I'd pick sweet.
The problem is, of course, that I don't like cupcakes. I've never really liked cake because it tastes to me like sort of rubbish bread that's been sweetened a bit, and icing on the other hand is too sweet, it basically just tastes like icing sugar, which is sweetness past the point that it actually tastes nice, like if you like salt that doesn't mean you'd enjoy putting a whole spoonful of it in your mouth.
Oh, also, inb4 someone mentions Cupcakes. I know a few people just stopped eating cupcakes because of Cupcakes, but it didn't really affect my appetite that much and it's been ages since I read the thing.
