Proton is WINE, it's a fork maintained by Valve and Codeweaver with DXVK (Direct X -> Vulkan) on top. If you use Steam for gaming it will set up proton automatically for you.

And yes macOS is a step up from Windows, but it's still a walled garden. Want to develop an iOS app? You must buy a Mac, you must buy a developer license, you must use the worst IDE ever created, and you must distribute it through the app store (except in Europe in theory, but they worked hard to make the experience so miserable that almost no one bothers).
