i think the issues that would be compelling for me are:
1. the 360 failure rate. if i'm going to pay that much money i don't want to deal with it breaking after a month.
2. the game library. get the console which seems to cater to your interests the most. this also includes online play. if all your friends play 360 online, then that should be considered.
3. what do you want to do with it? games vs games and movies. making the upgrade to a full hd entertainment center is expensive. you need a tv, 7.1 surround system to get the most out of bluray. that for some is too much hassle.
getting an answer that way will probably guarantee your satisfaction.
as for me we all know that i think the answers invariably lead to a ps3.
