Witcher 3 by a long shot. Dragon Age felt incomplete, lacked any redeeming characters, and had a useless story to boot. Personal preference here, but I also enjoy the Witcher's combat far more than Dragon Age's.
I use the Logitech G430's right now because it was only $40, and they do the job quite well. I know my dad has the Logitech G930 and he says he loves that. You could be hard pressed to find something that will conveniently work with a PS4 and a pc. I would never touch the PS4 gold headset, way too much gimmick going on there.
