In games where combat uses the bumpers a lot I bind the back buttons to that. For the rest of the games it depends on the what I find annoying to do repeatedly and end up mapping that to a back paddle.

For example on Breath of the Wild the back paddle was run which allowed me to run with one hand.

I’ve had the opposite experience, Steam Link app loses packets frequently and Moonlight works so smooth that you barely notice it’s streaming. I’m running Linux under Wayland so that could definitely be a factor.
