Joe,
Milky Way or Kit Kat?
Damn, that's tricky. I suppose you would have to take into account certain variables like my mood at the time, how hungry I am, etc. The Milky Way's nougat centre is far lighter than the Kit Kat's wafer centre, but then the Kit Kat just has that wonderful crunchiness. Right now I would probably take a Milky Way, but there's a good chance my answer would be different in the morning.
