I don't own a PS4 or Xbone. My cousin owns a PS4, another cousin a Wii U (it's currently at my place and I'm waiting for my to get here but something went wrong with the order apparently and it won't come soon. Dammit!), a 3rd cousin a Xbone (yeah, I have even more cousins... lots more). I've tested all 3 and some games and honestly, only the Wii U seems worth owning right now. Especially if you have even a mediocre PC. Neither the Xbone nor the PS4 have any exclusives that I would say are worth buying a console for. Everything else is a mutliplatform game that looks, runs and plays better on a PC.
Find a list of all the games that are out and see what's interesting for you. I've already wasted several hundred hours in Hyrule Warriors, Smash and Mario Kart. That doesn't mean you will enjoy them as well. Don't look at the hardware, look at the software and then pick the hardware that offers the most software you like. Buying a console for the hardware is one of the most stupid things you can do. Consoles are a "necessary evil" to run the games.
