2DS is ugly!
Ehh, I'd say that the 3DS is generally uglier than the DS (at least the lite and DSi models), but I agree that 3DS>2DS in that regard. I guess it depends on the color, but when it comes to looks, I still prefer my Vita.
However, physical appearance shouldn't really matter all that much (except color, but you can usually get one that looks decent enough), it's all boils down to comfort really.
