I moved from Manjaro to EndeavourOS and was been pretty happy with that. Unfortunately my study mandates things like .docx files, Visio drawings, things that just are more clunky to do if I'm trying to do it under Linux, so I've been actually using Windows 10 on my daily driver.
However I have LMDE on a second machine which I have been pretty happy with, although I am more of an Xfce guy than Cinnamon.
I can usually read them, though issues can range entirely from nothing to entirely broken. I otherwise haven't tried creating a .docx file on Linux (I would usually use .odf instead) and seeing how it renders in MS Office, but when it comes to an assessment I'd prefer not to test that.
