Less is more.
When looking for a new controller to replace my standard Xbox Series X controller, I had specific requirements. I wanted a controller that retained the shape of the original controller because I found it very comfortable; had the exact same d-pad (since I play Tekken), didn't want back paddles because they're generally not allowed in tournaments/locals and also had concerns regarding comfort and accidentally hitting them when playing fighting games, and had magnetic thumbsticks to avoid stick drift. All of the third party controllers out there never really quite hit all those requirements, and I was prepared to make a few compromises and shoot for a Scuf Valor Pro Wireless before I discovered Battle Beaver Customs. The fact that I could literally get a standard Xbox Series X controller with TMR sticks was a godsend.
For me, this is pretty much the perfect controller.
