PS5 pro - just works, decent 4K gaming, plays PS5 games and timed exclusives, remote play support, compatible with my PSN library / flash drive full of PS4 games. Reasonably quiet (though not as whisper quiet as original PS5.)

Steam Machine - pre-configured and easier than regular PC, decent 1440p gaming, plays nearly any PC game, remote play support, compatible with my Steam and GoG libraries.

Both sound good actually.
