Well, in my experience these things tend to offend somebody because their chosen product was not universally endorsed. Personally I prefer Xbox Live because it has more functionality. That is not to say that PSN is bad but there are too many limitations. I like being able to browse and purchase Xbox Arcade games from my laptop, my phone or even from my Vita. PSN does not currently allow for this. I would even settle for the ability to buy PS3 games from my Vita and have them added to a download queue that begins when my PS3 is turned on. Many times I bought an XBLA game while getting ready to leave work and asked my better half to turn the 360 on while I was driving home. I'd have a new game downloaded and ready to play when I walked in.
