I started prioritizing GOG a couple of years ago, buying most of my games there because I love their DRM-free stance. I have an entire backup of my GOG gaming library on my hard drive, so even if something happened to my account I'd still have everything I've bought from them over the years. On the other hand, their Linux support isn't great. For example, GOG Galaxy, their all-in-one frontend, is still not available on Linux despite being out for other platforms for years.

Steam, on the other hand, is DRM-agnostic, and there isn't an easy way to separate my games from the service. I worry about what would happen if I somehow lost access to my account. When a game is available on Steam and GOG, I opt for GOG each time because I'd rather have a DRM-free copy that I can control. Nevertheless, Valve has done a lot to support Linux gaming, especially with their recent debut of SteamPlay and Proton. Right now, Steam gives a much better user experience to Linux users and supporting Valve helps move Linux gaming forward. It also helps that their selection is much greater than GOG's, (though that's less of a pull for me as I do appreciate GOG's heavier-handed curation).

I'm torn because I want a little of column A and a little of column B. I keep hoping that GOG will eventually catch up with Steam with regards to Linux support, but that's already been the dream for a while (and a lot of people are done holding their breath). At this point I'm wondering whether I should just hop on the SteamPlay train and start putting my eggs back in that basket. Anyone have any thoughts? Who do you choose to buy from, and why?
