It's much more balanced than those other 2 imo. The bigger amount of RAM (1GB fully dedicated to games and 1GB to OS stuff) allows them to do more with less frequent (visible) loading times. That's something I already remarked and something they'll certainly use it to a very large extent for the next Zelda game.
And while Puppeteer is a nice looking game, it's still a 30fps one with some very hyrbrid/wannabe solutions to make impressive particles etc. (It does look nice and appealing, I really enjoyed the game and gave it a nice review) Wii U spits those one out more impressively and easier than ps360.
A modern architecture and being balanced really makes it shine when you dedicate enough time and love to it, like Nintendo does. So in that regard, it's more 'powerful'. But at the end of the day, it comes not even near to the ps4/xbox one in terms of raw power. And I think most people accepted that a long time ago.
