Gyro controls. They take a bit to get used to, but I can’t play any sort of shooter without them. Also back buttons if you don’t have the elite controller.
The touch pads aren’t something to dismiss either, having similar controls on my steam deck, they really open up the door to games you wouldn’t otherwise be able to play on controller. Steam input is really powerful, you can map them to all sorts of different inputs. For example emulating ds / 3ds games you can have the touch pads display a radial menu on screen that interacts with the ds touch screen in a specific pre-defined way depending on what you select.
But ultimately, I want a controller with gyro controls and back buttons that’s easy to map (read steam input because it changes mappings automatically per game) so my only options are the dual sense edge or the steam controller.
8bitdo is great I have a couple of their controllers, but they don’t make anything that’s feature-competitive.
The only thing close is the dual sense edge, which costs twice as much. I have one and I bought a steam controller to replace it because the track pad is in an incredibly awkward location to the point I basically never use it and the battery life sucks
