Chat features- XBL clearly. Cross game chat & parties just aren't happening until PSN 2.0 (ie, PS4). I have no clue what Sony are doing or in this case, why they aren't doing it.
Updates/patches- Usian Bolt vs fat dude with hepatitus.
Marketplace/Store content- Both good, the Store's only real failing is lack of demos across every title.
Stability/smoothness- I have gotten less disconnections with PSN but on the whole both have been fine for me. PSN gets marginally more dedicated servers than the service which costs £40 p/y. So thank you for not much at all, MS.
Other features- Home, internet browser, BBC iPlayer/4OD, Vidzone, Mubi, remote play vs Sky player and stuff I can't remember. I don't use any of this extra stuff much but PSN seems to have more of it.
I won't say I like the PSN itself more than Live but I'm not renewing Live next year after paying for 3 or 4 years. I do prefer PSN's way of unlimited online gameplay without thinking about subscriptions or renewals.
