I've heard bad things about the PC version. I've got the 360 version, and it's pretty awesome. It does take a bit of time to start heating up, and the cars are, shall we say, more "realistic", but once you get used to the controls it's no longer an issue. It may not have the sheer amount of content that San Andreas did, but to be fair, it's the first game in the current engine, and it took three games for it to get that far with the last engine. If they keep up with the DLC then it'll improve vastly with time. If you've got a console, and a hankering for GTA, don't get the PC version.
