I prefer PC when it's not a game that's only on consoles. I have a iMac I game on that can run a lot of current games out there with windows on it. Also play on my brothers gaming comp if he has a game on it that I want to play. As for bug support, I do not like games that can't be updated. A few console games i've played have freezes on them in some loading parts that you go through often which can be very bad (very bad as in get far and can't save). And controls.. I don't care to much, but mouse/keyboard is a lot easier for FPS's and such.
PC has got to be the best, it's opensource and you get a lot more games then a console does. Plus you even get emulators which is virtually a console in a way. I play MineCraft, CoD: MW3, APB Reloaded, Catacomb Snatch, BIT.TRIP RUNNER, Brawl Busters, Fallen Earth, Realm of the Mad God, Terraria, Garry's Mod, Left 4 Dead 2, Team Fortress 2 and CrimeCraft... And a lot MORE!!! I also play other online games such as Happy Wheels. But that's as far as it goes. Consoles however are limited. Although you can get Indie games, most of them are not free. Whether on PC some games are in BETA stages so you can just test out by asking the devs. Overall PC GAMING is the BEST!!!
For me, since the only game I play is Modern Warfare 3 on PS3 I stick with console. If I had the more time I would invest more money on my gaming rig.
I mainly play on my PC but I really enjoy the simplicity of consoles. PC gaming gives me such a headache because I'm never satisfied. Between Eyefinity, Crossfire and mods I spend more time trying to get my games to work than actually playing them it seems haha. But when everything is working to my satisfaction, PC is king.
I use my 2nd-Gen i5 powered laptop, with Nvidia GeForce GT540M and 6GB of RAM, for gaming; Especially nice since it's way above the minimum system requirements of most current games. The things that I like about PC gaming are: a) ease of controls, b) game mods to give variety, instead of playing a monotonous "vanilla" game, c) I don't have to buy some ridiculously-priced console to play a game.
