Definitely on PC, but I hope this doesn't turn into a fanboy rumble!
I've also been a PC gamer most of my life. Was playing Taipei on my Windows comp back in 1990 as a 2 year old, have been loyal since. Sure I spent at least 15 of those years playing on a POS where I played almost every game on the lowest of settings and still had stuttering, but I didn't care: I did it for the experience. Once I finally became old enough to get a well paying job, I bought this rig about a year ago and haven't stopped gaming since. Like Kur said, mods are just a bonus, it's the PC that I just love playing.
Really I only have ONE complaint with PC over consoles, and that's movement. Though I think moving/strafing + aiming is infinitely easier on a PC, for most games there isn't a way to slowly "increase/decrease" movement. For instance, you can't just lightly press a key like you would slightly move the stick/DPad/whatever to move slower than normal. You either move or you don't. This is mostly just an issue in stealth games, and generally games cater to this fact, but I'd still love to truly creep up on baddies instead of walking normal speed and killing them. But the great thing about next gen consoles is the controllers are wireless and can pretty much just be turned on and checked to use on a PC. Gotta love the future...
