NC 22 - NextCloud office?

I am currently using NC 22.x.

I learned recently thet NextCLoud has made their own version of Collabora Office to work well with NextCLoud.

1 - what are your thoughts on it?
2 - we are looking at installing an office suite, and there are 3 of them now: only office, nextoffice and collabora.

What are your thoughts as per functionality, as well as ease of installation?

We recently; learned the hard way that the app store version of OnlyOffice is not for production use, and since learning of NextCLoud office I’d like others feedback before installing one them.
