IMHO with a couple of fixes which allow Linux+Wine to better simulate some specific lowlevel Windows behaviours (like this one recently in the news: https://www.xda-developers.com/wine-11-rewrites-linux-runs-w...)... a Linux distro with a 'Windows personality' (e.g. running Windows Explorer as desktop) should be pretty much indistinguishable from native Windows.

In the end it's all about driver diversity and quality though...
