The 360 system updates were a little better (generally not so huge). The game updates were insanely better, a few MB update on the 360 could be a few GB update to the PS3 version of a game. The 360 I think allowed handing updates as just pushing delta's (changes) in the code and not a huge amount of code.Time will tell what that looks like on the new systems.I will admit the xbox updates are hands down better than the Playstation and least on the 360 vs. the PS3.
