Well the WiiU is my primary console and personally I'm pretty satisfied with it. I'm thinking about a ps4 down the line.
I think if the wiiU makes a good secondary console as well comes entirely down to the kind of gamer you are. Do you like Nintendo games and want to play them? There. WiiU is the perfect secondary console for you.
Lets be honest here for a second, the Xbox and the Ps4 share significantly more overlap with each other than they do with the WiiU. If you want the broadest possible gaming expierence out of two consoles, you should go with the WiiU.
However if you don't like the kind of games Nintendo makes, the WiiU would be a horrible choice for you, seeing that at this point Nintendo first party is basically it's sole selling point.
Now why anyone would want a ps4/xbox one setup is a mystery to me, unless you're an avid Halo fan that for some reason went with the ps4 at launch, or you just want that 1080p multiplat experience on the ps4 but got the xbox at launch....maybe? None of the two have enough must-play exclusives to warrant buying them both at the moment imo.
As it stands I'm personally the least interested in the Xbox, it has, as of this E3, three games I'm potentially interested in and those are Ori and the blind forest, Cuphead and the new Keiji Inafune ip. Those don't justify a console purchase for me though.
