I prefer PC for its versatility, customization options and plethora of peripheral options. But if you stick a Playstation or XBOX controller in my hands, I won't bat it away like it's somehow the plague.
I personally am an Xbox guy. Had a Ps2 way back but then moved to the Xbox and have not looked back since. I only use my PC for editing and regular stuff.
Personally I prefer PC due to the variety of games and customisation. Plus the fact you can use a large variety of controllers on PC. However, when I am gaming on a console, I personally prefer PS4.
All of them only cos i own and plan to own games across various platforms so i can make use of my gaming
Wii u - mario kart 8 and super smash bros
Ps4 - fifa 16/ metal gear phantom / bloodborne
X1 - forza 6 / witcher 3 / halo 5
Pc - hots / battlefront / legacy of the void / fallout 4
If i have to choose one (and i dnt want to) then halo 5 for sure
I really dont have a favorite platform to play on. PC is good with its options, Consoles are good for Couch gaming, even thought all I play on my PS4 is Dark Souls and Bloodborne. What ever makes you happy gaming on is all that matters.
