I've only used CrossOver on Linux and actually find it harder to use than Lutris. There's some crazy stuff like needing to declare environment variables inside a configuration file instead of having a GUI for it. But if you look at CodeWeavers' blog and release notes, you'll see them constantly making changes to improve gaming on macOS. That's where they seem to be devoting most of their energy these days. CrossOver on Linux worked for Microsoft Office when I needed to use it, but that was the only reason I bought it.

I still think it was a worthwhile purchase, if only to support further Wine development. CodeWeavers has a great article about the differences between CrossOver and other Wine distributions: https://www.codeweavers.com/blog/alasky/2019/3/21/wine-crossover-and-proton-whats-the-relation

PlayOnLinux is no longer under active development (even Phoenics seems to have been stale for a while now), and Steam's Proton, Lutris, or Bottles are what you should use on Linux nowadays.
