It's true. If you have a decent PC, the Wii U will serve your console needs.
I guess it depends. I have a 2015 Alienware laptop I got a few months ago and the desktop I built last year has 8 cores and a sick graphics card. I also own a PS4 and a WiiU because I find PC gamers online very ANNOYING. PS4 kids can be annoying sometimes but I have this feeling that a lot of PC gamers probably never get out of their house or shower for that matter just by talking to them.
