I’m not OP but I use GOG significantly less ever since I switched to Linux and got a Steam Deck.
- Steam has an official Linux client, GOG does not
- Steam syncs my savegames between PC and Steam Deck out of the box, GOG does not
- Steam setups all the Proton-stuff and I only have to click play, GOG does not
I currently use Heroic but until GOG commits some more resources into their Linux ecosystem I’m just going to use them sparingly.
