Steam

Some functionality that keeps me using the Steam Controller has been touchpads for movement, quick gadget swapping with touchpads, quick 180s/gyro activation with touchpads.

I use it to play games like Doom Eternal, Left 4 Dead 2, Spin Rhythm XD, The Finals, etc.

Sadly I don't find myself doing the same on the Steam Deck opting for the joysticks instead, since I don't find the placement, smaller size, square versus circle, and flat surface versus concave offering the type of consistency that I use the touchpads for on the Steam Controller. It feels more a touchpad appropriate for slow paced games or just desktop navigation than optimal for the way I use the touchpads on the Steam Controller. And I don't see Valve delivering on the touchpad end that I would like with the next Steam Controller with all the inputs it would be fitting in.
