For what they did this Generation:
1-Guerilla bcs of Killzone 2 and 3.
2-It is technically not a Sony studios but I like what Insomniac did this gen (Ratchet, Resistance)
1-Sucker Punch (Sly Cooper !!!)
2-Naughty Dog (Crash Bandicoot,Jak)
Strangely I'm the only one who doesn't like infamous and Uncharted.
