Well, I decided to give the SoftMaker Office 2021 beta a look and downloaded a copy.
(I only tested the TextMaker app since that is the only app I'm interested in.)
The suite is definitely more polished than their 2019 version which I also have. Highly configurable both with the Ribbon and menus. Also supports dark mode.
Lots of templates to use.
However, when testing with my older Word documents, the same problem that I ran into before is also present in this version. Indents, margins, and page breaks on complex documents are way off. The older Word documents converted and could be edited, but mostly had to be redone in order to maintain the original content and look.
So again, I decided that I would rather stick to MS Office for compatibility purposes and occasionally use Pages for documents that I originate for myself.
