PS4, already built a library these past 3 years. NX won't be as powerful as the PS4 nor have the online ecosystem like PSN. I will also play the indies on it for the convenience. Got Shovel Knight disc release on PS4 instead of Wii U.
The last time I bought multiplat titles on a Nintendo system was the Gamecube, many multiplat games were better than the PS2 counterparts.
Switch is just for Nintendo games for me.
