I used a windows version of Open Office for years before changing to Libre. Can't recall why I changed.
Probably because it is more advanced than OOo. LibreOffice has far more developers working on it to update it and find loopholes that may be used by others to ge into your system.

As Peter said, Libre Office has more ongoing development work. The last release for Open Office was December 2023.
I don't use either because my MS Office 2013 still works fine. Apparently Libre Office has a ribbon style user interface, like the more recent versions of MS Office, while the user interface for Open Office is the older style. From what I read, familiarity with the old interface is virtually the only reason to choose Open Office.
