I have the xbox 360 on a wired connection and my ps3 on a wireless connection. Both pretty much download demos at the same time. The only reason it takes longer to play on PS3 is because I have to install after downloading. People who say PSN drops just try it on a wired connection and see what happens.
People use "game lags on PSN" as an excuse to justify their purchase of xbox live. In reality however, both give the same performance. Sometimes PSN gives a better performance because many 1st party studios use dedicated servers. I have been buying xbox live memberships since 2006 and my membership will run out in a month. I dont think I will buy another membership until gears 3 comes out because I really only pay for live to play halo and cod online.
I also just recently started playing games on the PC and I am amazed how awesome the STEAM service is and its free! And I dont have to pay $50 for cross game chat because I can just use skype which is alo free and has better audio!
