So what you're saying is that the PS4 is a powerful console without games?
I think it may just be poorly phrased shock that you'd make such a comment, as for most people the PS4 lineup seems patently superior to Wii-U.
I've got both systems (and XBOne), and though the kids enjoy a few more games on the Wii-U, I'm basically stuck waiting on Zelda Breath of the Wild.
On PS4 I've got Bloodborne, Dark Souls 3, Witcher 3, Dragon Age 3, Uncharted 4, Until Dawn, Rise of the Tomb Raider, and quite a few more - with more on the way too (Horizon Zero Dawn, The Last of Us 2, etc).
Granted, I'm sure it's subjective and based on what types of games you enjoy, but it's just hard to imagine anyone looking at the current console gen's library and thinking WiiU is the one with the good games.
