@Soapy I want to give you a third option, orange pi neo x86, a Chinese handheld that has Xbox layout controls with trackpads and with a better Apu then ex Z1 and deck apu
for example, botw on the Ally, that "pebble" shrine which you have to control the table to get the ball to the end I couldn't hold the pebble table still on the Ally, it kept going when the device was being held still that didn't happen on the deck
