I'll take a stab at this:
* Achievements/Rewards - Does the console you own encourage you to continue playing? PS360
* Console interface - Does the interface draw you in or do you feel lost? PS360
* The online service - Which online service keeps on delivering and meeting your needs? Don't care for online. I guess PS3 because it's free
* Multiplatform games - For which console do you prefer to purchase Mulitiplat games? Depends on which version has less flaws
* The library itself - Which library offers the most diverse selection of games? I have more 360 games, so 360
* The controller - Does the controller make the experience more worthwhile? 360
* The exclusives - Which console boasts the best and most inovative exclusives? Looking to the future, I'll give this to PS3 since it has more interesting exclusives for me personally
