I tried Crossover and it kinda sucks.
WDYM? It's Wine like Wine. With a GUI similar to PlayOnLinux and such.
I suspect Steam lacking Proton is the main reason you don't like it. That's easy to get used to, yes.
That might be, eh, sort of a business agreement between Valve and Codeweavers, the latter play a significant role in upstream Wine's development after all. And Crossover is their paid product.
