Where not argueing which is better, just in which categories each has its strengths. yes a PC game will look better then its console counterpart, but at 4-6x the cost.
As well as preferences, i hate using the keyboard and mouse, i've used consoles since i was 8 years old, and am used to the controller. Just got into PC gaming when i was around 15, so its more natural for me to use a controller over a mouse/keyboard. But for many it is the other way around, which is cool, its all preference.
As i said before, the thing i love most about consoles is playing with 3 of your buds sitting next to you, not nearly as fun as playing online with friends.
One last thing i think i should mention on consoles behalf, is the fact that when you get home with a new game, you just stick it in the console and play. never have to deal with unknown system crashes, never have to try and optimize your computer to match the game, just stick it in and it runs.
i dont mind screwing around with my config sometimes to get the best performance out of my games, but sometime its just too much and i just want to enjoy a game.
