Oh man, 360 on the net is the best. Free demos to try before you have to buy or rent, or months before release?? The online content and interaction between players is so much ahead of the PS3 network(Which it should be considering the number of years XBL has been around).
But what is horrible is the online experience of the Wii. EGM did this article on how slow down cripples Super Smash bros online to the point that the game is virtually unplayable. A game to be played with friends, when played with friends online, is unplayable. And the friend ID number system to find a player on the net is laughable. And in interviews, Nintendo says they just don't really care.
It's as if their customers are saying:
"Oye, we really want this. In fact, we demand it."
And there response is
"That's nice. Cake?"
