NeoGaf was much more of a Sony forum in the early days, but during the Wii/DS era it became more neutral to Nintendo and Nintendo is widely considered the best game developer on the board I would say (EAD Tokyo especially). NeoGaf is pretty enthusiastic in pushing games like Mario Odyessy, Splatoon, Zelda: Link Between Worlds, etc. 

Nintendo still takes crap for a lot of stupid/odd business decisions it makes there, but that happens on every board.
