Sony 1st and 2nd party developers, which are your favorite developers

[Groucho]

Best 1st Party: Team ICO, Naughty Dog, and Zipper.
Best 2nd Party: Insomniac and Sucker Punch.

 

If I had to vote for my two favs... Naughty Dog (1st party) and Sucker Punch (2nd party).  Although Team ICO and Zipper take the cake as far as technical prowess goes, IMO.
