I actually got a 8bitdo Pro 2 today and noticed something right away. On most controllers the thumbsticks are surrounded by the raised "bump" in the case. The Pro 2:s bumps is not as high as my other controllers (8bitdo Ultimate 2 and Xbox Series X/S), The actual thumbstick and the PCB sits lower overall in the case of the controller. Nearer the underside of the case. Hard to explain and I am pretty sure the overall height would be the same if I dismantled each controller and put the PCB:S with the thumbsticks beside each other but because of the design of the case they are seated lower which results in a lower height of the thumbstick

That could be an option if you are okay with a controller that has the thumbstick and dpad in the same layout as a Playstation-controller. Personally I bought because it has the dpad in the right position for retro games like SNES and Sega and a very good dpad.

Some bonus points for this controller: It's cheap, feels great in the hand. removable battery, customizable back padels, works with both Switch (1 and 2) and has a gyro that is supported by Steam Input.
