You're going to get a lot of advice here, based on personal preferences and that's what it's down it. Depends on the types of games you prefer cause ultimately a console is only as good as its games.
I'm going to recommend the PS, based on my personal experience. I'm not much of a FPS player and most exclusive games for the box seem to be taking that path. You get Blu-Ray, which, if you enjoy watching movies, will wield better results in terms or audio and video quality. Depending on the version you buy, you also get built-in wireless and backward compatibility and most games are free to play online. I personally prefer the PS controller.
Now that most major companies have ceased to release their movies on HDDVD, the PS is a little more future proof in that it's a little clear what is going to replace DVD's. (But this isn't a given fact as something better then Blu-Ray could be released)
