OK, so this thread isn't going to go well, but I'll give my 2 cents.
Reasonable people know that the WiiU is weaker than the PS4/X1. It has some nice features that give it some minor benefits but it is weaker in most ways that count for devs and third-parties are going to struggle to get multi-platform games working well and looking good in a timely manner.
It should theoretically be more capable than PS3/360 (doing more with less raw power), but until we have tech heavy games specifically built from the ground up for WiiU, no one is going to be convinced no matter which side of the fence they sit on. Monolith Soft's X will probably be the main one.
