I prefer Heroic Game Launcher. It detects GPTK if installed and compiled via homebrew, but also has a built in downloader for different wine binaries (crossover or verbatim wine). You can set each wine runtime for each game. Plus, Heroic can login and download your Epic and GoG games.
Probably correct, I am a steam user of course but I always prefer to buy games on GoG (because of the DRM-free situation). And possibly because a lot of my steam games already run on Mac natively.
