It’s more convenient and I can’t afford a high end office chair for the desktop. The last few used ones got scooped up even in bad condition. I’ve tried the car bucket seat type and even have one from a workplace ‘boomer execs trying to be hip raffle event’, but car seats are generally uncomfortable to begin with.
But yeah the deck is pretty excellent for anything it can maintain a stable frame rate with and I use it even when performance is a bit iffy. I tell anyone considering one that it handles like a wiiu gamepad with better button placements though.
