I don't go in for the current "master race" bullshit. I think that mindset has just gotten a lot more popular because the PS4 and XBOX ONE were such let downs (technology wise and business model wise). I have always played on both and i will probably continue to do so with my PS3, there would have to be some pretty killer exclusive title for me to pick up a new console and pay monthly for the internet that i already pay for.
On PC: better graphics, customization, mods, bigger online matches, steam sales, countless other things. I just think the Sony and Microsoft are getting greedy and milking their players for all their money, i foresee it getting worse.
