Lutris was pretty janky IME. Bottles has similar issues with Lutris and some very bizarre UI decisions (like IIRC you can't delete bottle snapshots from the UI, so unless you manually go and delete them in the filesystem, creating snapshots just takes up an ever increasing amount of space). Honestly Heroic is kind of janky too and throws errors about login status half the time, but it generally works at least when it comes to launching the games. The problem is Steam almost always just works, and if it doesn't work it's pretty much always the game's fault and thus I would have problems with any launcher.

Can't play Stellaris through Heroic because of the launcher being broken.

Bypassing the launcher requires some convoluted setup, and it also removes the ease of modding.

Manually installing Stellaris through Lutris works, but Lutris isn't well maintained, and even though it's connected to GOG, doesn't update Stellaris. Says it can't find updates despite there clearly being one.

I thought more of Lutris and GameHub, forgot about Heroic. There's also Legendary and Cartridge but i don't know them.

I use heroic to install and have the setting on to auto add them to my steam library
