Probably the best thing about Live is the ability to play against other people online easily and quickly on a console. The reliabilty is fantastic as well, very little lag in most games from Microsofts side of things. Overall Live's ease of use is astounding. Setting up, connecting and playing are all acheived very simply. Plus, the ability to quickly and easily locate friends and get in games together is quite useful. Especially because that same friend's list is used in all games.
