or you could set the mouse on one of the touch pads and mouse clicks on the back pedals. then you do not need to switch the profile
i think the main difference is the ui itself. emulation station looks great but is build for a console like experience only. with emuze the ui is more simplified with the sidebar for your systems and a main part with a grid of your games. i like this simplified approach more. on top of this it is usable with a mouse like a typical desktop application but also with a controller on a tv.
you could give emuze a try: https://github.com/bmsuseluda/emuze
i worked on it for about 2 years and released it a few days a go. it is a passion project of mine. maybe you like it 🙃
as a workaround i put the steam deck in the dock without puting the tv on. with this the steam deck can download with display off.
the left side of my steam deck was very unresponsive. i returned it to valve. the new device i received works like every other touch device i have.
