I did think that PSN community as lifeless whenever I played COD4, out of 5-6 games I maybe met one or two people that made constant annoying fuzzing noise through the microphone and generally no one spoke, whereas on Live, every second person has a mic, so there is always an American to argue with or bicker with random people, although I think that's mainly due to the fact that every 360 had a microphone included whereas I don't think the PS3 had a bundle with a microphone in it.
I thought the connection speed(The speed at which the network finds a game) was relatively the same, in some cases Live being marginally better, but by a small non meaningful amount. It's the connection stability that got to me, on PSN the amount of times I got disconnected during sessions or even on MW2, when the connection was trying to find a new host and couldn't do so, therefore ending the game altogether. Although what I find annoying on Live is lack of BBC iPlayer, and 4oD(I couldn't care about ITV, the chav's wet dream television)
Imo paying for Live is a negligent argument as it works out at about 13p a day, playing about half an hour a day you can get more than your moneys worth, and I'd rather pay for a more stable service with considerably less amount of random disconnections.
ALSO: Parties - Oh my god, no matter how much PSN users say they don't give a damn about it, they cannot even begin to comprehend how awesome it is for the community. Cross Game Party Chat is just awesome, and I am genuinely surprised it hasn't been implemented into the PSN yet.
Disconnect and self destruct, one bullet a time.
