This is so friggin' retarded. People on PSN don't sound immature because 3/4 of them don't SPEAK. No headsets. The people who do buy headsets are probably going to be more into gaming and have extra money to blow on a BT headset. Overall, I'll take the jabbering retards and mute them over having 2/3 of my team not communicate at all.
On the other hand, I have yet to see a console game rival the maturity level of the guys who were serious about simming in Forza. That was a fantastic community that I haven't seen rivaled by anything else on PSN or XBL.
