There are many games where you use the camera constantly. FPS, top down shooters and third person all use the analog sticks more than the face buttons. And I’d argue that’s the bulk of gaming nowadays.
I also have a pro controller with back buttons which allows me to move the camera more freely while having access to jump without taking my thumb off the stick. You get a lot more flexibility that way.
The Xbox position of the left analog stick is really uncomfortable for longer gaming sessions when you are used to the PlayStations more natural thumb position.
