You can also try LibreOffice, which is free.
Thanks, Deozaan. Our organization has gone to LibreOffice in an effort to break free from Microsoft, so I use it as necessary. But it is sometimes surprisingly different or simply awkward in the way it works. It is fine as a free Office suite, but I would never use or recommend it specifically as a replacement for MS Office. That's why I want to try Softmaker Office. If it is as similar to MS Office as I have heard, I would rather pay for it than use the free LibreOffice. (Yes, I know Softmaker has a free version, but I need the more advanced capabilities of the paid version.)
I use both: Softmaker Office is much more compatible with MS Office. Libre Office's compatibility is so-so to poor in my experience. ... I'd highly recommend [Softmaker] if MS compatibility is important
Thanks, Tomos, for that confirmation. Yes, compatibility with MS Office is important for my use, so that's another reason I don't want to go with LibreOffice.
