Unfortunately, I don't think either is particularly great. LibreOffice looks horrendous, performs at or below average, and does not have fabulous compatibility with Microsoft Office formats. On the other hand, ONLYOFFICE has better compatibility but feels cheap and pushes web services.

If this is for personal use, I would go with LibreOffice. If you need to share documents with others using a common format, go with ONLYOFFICE.

libreoffice

I've been using LibreOffice for a number of years without issue. Literally takes care of all my word processing and spreadsheet needs. I don't miss MS Office at all, which I use daily at work.

LibreOffice

LibreOffice unless MS Office comparability is the most important thing. Then maybe try ONLYOFFICE.

Both are good, but different focuses. OnlyOffice has fewer features, but extremely good MS Office cross-compatibility.

Libre Office has more features, but can run into compatibility issues when going back and forth between MS Office.

That being said, for the average user's needs, both are perfectly fine.

OnlyOffice is also able to be used in a cloud framework similar to Google docs, but to my knowledge Libre Office cannot do that.

I use OnlyOffice and enjoy it. I do notice some fancy features missing but as I'm not a power user it doesn't bother me. I've opened OnlyOffice docx files in MS Office and vice versa many times with no issues ever. I've also installed MS fonts on my Linux distro and they work in OnlyOffice. I don't notice it pushing online features like somebody else said

I use Libre Office. I have zero need if back and forth with enshitified MS Office.

LibreOffice should receive more updates than ~~OnlyOffice~~ OpenOffice.
I switched my uncle from ~~OnlyOffice~~ OpenOffice to LibreOffice (for work) and he never complained.

Edit: I've confused OnlyOffice with OpenOffice.

Anyway, I have both LibreOffice and OnlyOffice. I always use LibreOffice but for one file (yes it is an excel spreadsheet) I need to use OnlyOffice 'cause Libre can't open it.

Is it possible to download just the word processor (libreoffice's) and nothing else?

Try both out as flatpaks if you're on Linux and keep the one you like as I did :). I think both flatpaks come with the full suite.

I ended up sticking with OnlyOffice and feel it will probably work better for most people doing things like writing documents and spreadsheets with various formatting, tables, charts, formulas and equations.

I am mainly a Google docs user (and in the past MS office) as most people are and the OnlyOffice UI and workflow is much more comfortable if you're coming from these products. Things work and look the way you would expect. LibreOffice UI feels very clunky and dated (even after trying different layouts). For example, charts look really bad by default in LibreOffice. OnlyOffice seems to work pretty much just as well as gDocs/MS office so far in my limited experience for most scenarios.

As part of my effort to reduce reliance on gDocs I am planning on setting up a self hosted Nextcloud office instance and it is based on OnlyOffice so it is more motivation for me to stick with it!

LibreOffice for local files, OnlyOffice for cloud

I had issues with Onlyoffice taking ages to load documents with lots of pages while Libreoffice did it instantly as expected. So back to Libreoffice for me.

@t0mri I have both. and i use both in different situations. depends on the specific document.
