Doritos Nacho Cheese doesn't really taste like nacho cheese to me, just sortofa powdery cheese like product. Last Call Jalepeno Poppers taste like real nacho cheese with diced jalepenos.
I wouldn't regularly buy them but they do succeed at imitating a jalepeno popper. They're good for a Jelly Belly type experience, "hey, they really taste like what they're supposed to be."
