Disguises Tilesets are hard to use if you're inexperienced enough. Agamas' tilesets are more sophisticated therefore better and harder to use. I don't find Agama's Tilesets very hard, Egypt is a bit of a challenge to get used to, though.

If Disguises Tilesets are better because they're easier for most people then Tic Tac Toe is better than Chess.

EDIT: For thoose who say 'less' cartoony tilesets are better: You don't belong here.
