Neither, they're both in a launch title funk still.
Second Son is alright but the gameplay is dated, Titanfall gets old pretty quick. Dead Rising wasn't all that great, Ryse and Knack were flat out bad. KillZone should have been much better than it was, and Forza was a step back for that franchise.
It's like comparing whose crap smells less bad, who cares, they both stink. In the past Microsoft had a pretty good knack for picking out exclusives (They wound up with Halo, Gears, Fable, etc; ) and Sony always seemed to be playing me too (KillZone was no Halo, Uncharted had 1 truly great entry, uh, I dunno, Infamous is obviously no GTA.), Metal Gear Solid was an exception for a while but that series has become a joke of previous itself, but right now they're both pretty weak and neither has a particularly promising line-up.
I anticipate that will change soon though, especially with E3 around the corner.
