Seems like every week over on GamingOnLinux there’s an announcement of a new launcher.
Personally I only use Steam & Lutris. Lutris for my gog games and BattleNet, Steam for everything else.
I don’t know of a good reason to use Heroic, or any of the other new ones over Lutris / Steam, but maybe I’m missing out.
Honestly I’m not totally sure, I’ve heard that it handles sand boxing differently but I don’t know the details
I just know that on occasion I’ve had some windows programs fail to install while using lutris, and I’ve tried bottles and it worked, I probably could still get it to work in lutris if I tried, but It works most of the time in my experience so It’s the first piece of troubleshooting I try
