In contrast to Raging Lucario, I believe PSN has more annoying people and this is only helped by it letting you here people over the mics even when you aren't using yours. At least half the games I've played or watched on PSN have some Gangsta Rap going over the mic.
I think the 360 has a better range of games and is much better value for money too.
MAG seems to sway it PS3's way in the future I must say. I'd state that Natal would be better but, to be fair not much has been announced about Natal and it could simply work awful.
Anyway, 360 for me but I'd settle for a PS3 if there was no 360. D:
Like I siad last time round, I think it's more the games you play online than what what service you use. I've found more jerks on 360, but I've come across a lot of them on psn as well, it just depends what games.
I had been on PSN for a few years before I got XBL, and I can say that X Box 360 is by far the better choice for communication and making friends. The thing is, with PS3, you dont have to worry about RRoD, although, my dads is no longer working for mysterious reasons. They each have their advantages but I prefer my 360 Elite.
I Pefer PS3
Since It Has Free online Usage.
Also has less Games but It Comes With better Graphics.
Better Conection VIA Controllers.
