I don't have problems with switching Windows using alt-tab. Plus, you can customize it to meet your need. Please refer to the attached screenshot.

"(https://en.wikipedia.org/wiki/Usage_share_of_operating_systems @ 2021-20-12)) That means that Alt-Tab is the defacto world standard. Now, I very much don't like Windows and Super-Alt might bwell e a better option than Alt-Tab, but the world would be a better place if there were more standardization. So ... please swallow your pride and get with it!
