Also I heard the game is absolutely terrible on 360 and PS3 and PC.
What? Where did you hear that? I've enjoyed the game so far, ain't had no problems such as lag or the game freezing.
On PC, there's still a plethora of bugs and the like - despite the updates, people are still experiencing crashes, freezing, bad hit detection, EMP effect making the game unplayable, even the latest update made it so trying to play with SLI removes all foliage, reduces texture quality massively, sometimes removes water, the ground texture flickers and so on - apparently not an uncommon issue, but for anybody trying SLI.
For consoles, they still have sounds coming in in layers slowly at the start of the game, crashing/freezing, joining lobbies itself can be bugged and more of the same from launch.
That makes it sounds more than it is, it still works okay for the most part (sans no sound at start of game), I'd otherwise notice nothing wrong if I only played a few games.
