I was an Xbox user for a long time (Original Xbox Softmod FTW!), but never did Live in earnest, which started to annoy me when it started to become required for certain apps (like Netflix). I tended not to bother with the multiplayer side of stuff, so the major draw of XBL was moot for me, but I was essentially being told that I needed a subscription service to access a subscription service, which irked me somewhat.
Started using my gf's PS3, and eventually got one myself, and found that, in spite of not liking the controller, I generally preferred the interface and use of the PS3, and there was a legitimate reason for me to get PS+ (free-ish games!), combined with the offers and various other bits, it made it easy and cheap.
From a technical standpoint, the consoles aren't too dissimilar, for my purposes. The major difference is the Kinect, and the tuner stuff, which would be fine, if it was going in the living room, but as the consoles go in our office, where we can both be gaming together or independently, it's a little pointless (plus the fact that MS apparently didn't work out that anywhere not on the US display frequencies might need a little extra consideration for these things). Both consoles announced that it's more or less a clean slate deal (no backwards compatibility), so there's no value to loyalty, and the PS4 seems to fit me better.
There's also the fact that I have issues with MS decisions in a number of departments of late, but that's a topic for another time.
