Do you play e sports? Or you just play casually? For e sports i recommend Logitech, Razer DeathAdder Elite Rival 300 / 310 (mine) or Zowie Ec1-a / ec2-a. If its for casual games just pick a confortable one of good brand, its enough. For keyboard if its for esports, get a fast response one like mx brown or red (pretty silent too). If its for writing and playing normal games you can get mx blues or greens that have a very satisfying typing experience. All of this is my opinion ofc
