The experience using Heroic Games Launcher is a good bit less polished than Steam IME. I only really use it to play games that are occasionally given away on the Epic Games Store for free so I mostly treat it as a nice bonus if they actually work on Linux.

I use it almost exclusively for Satisfactory, which I could buy again on Steam, but I don't want to.

Steam is working flawlessly. Other than anti-cheat, I haven't run across anything that doesn't play exactly like its windows counterpart.
