With the use of Heroic game launcher, I’m wondering if you all preferred to play your GOG version of games over the Steam version. I can go either way but sometimes I pause and think, having two copies of the same game, one on steam and one on GOG, which one would give me a better gaming experience. For example, I may choose the GOG version because I don’t have to deal with pre-shader work being downloaded every so often and support DRM free gaming, owning my games. Take the game files anywhere I go. I can just into my games. Yet, Steam achievements and seeing the game’s metadata is always life: seeing the game info, store page, community stuff about the game, and more all there. So what do you chose? GOG game or the Steam game.
Lutris, I’d say. You can login in Lutris to gog, and it pulls all your games, so you can choose. Since they are already identified, you can choose specific lutris installation scripts for them. Then it’s about as simple as right click on the lutris game - add Steam shortcut.
