I don’t gave a lot of use of it in my personal life, but I did switch from LibreOffice over to OnlyOffice and have been happy with it. The interface feels relatively modern and logically laid out. My spreadsheets tend to be basic tracking sheets and I haven’t made a written document file in ages, but for my modest needs, OnlyOffice is a clear winner.

I use it in my nextcloud. I really like it. I tried to use libreoffice, but I didn’t like it.

I’m a heavy user of spreadsheets and in my experience OnlyOffice is inadequate in features, it’s slow, sluggish, and crashes whenever you try to open anything big. I’m surprised it gets so much attention and I can only assume it’s used by people who don’t do any really heavy-duty work with it. LibreOffice is full-featured and is what I’ve been using for years, I’m very happy with it.

Bit buggy printing and slower than shit to load. But once it’s loaded it generally works OK. A better one is WPS Office, but it’s Chinese and proprietary, though free (as in beer). LibreOffice is meh and printing doesn’t work great on it either.

I personally don’t, but a friend told me it’s his choice for his pop os laptop when he has to work with clients who use Microsoft products. Sounds like it has the best comparability, in his opinion.

Also have a look at SoftMaker FreeOffice. The older 32-bit versions have worked well for me in the past.
