They look perfectly fine to me, though I'm personally a "style" person first and foremost.
This is going to be one of the rare times I agree with the OP. The power thing only turns into a flame-war if Nintendo fans let themselves get drawn into the battle. Yes, power is very important, as it does drive game-play, but the Wii U seems plenty powerful for Nintendo games. If it's the best looking next-gen third-party games you want, then you should probably look into a PS4/XO, but if you're happy with what the Wii U brings to the table, then you're better served ignoring those who disparage it for being weak.
