Nobody should use OpenOffice. It is just an an ancient version of LibreOffice at this point.
The name OpenOffice is much better. Many people every year probably get pulled into OpenOffice without realizing what it is. I hate that Apache is just sitting on that codes and pretending it is still active.
Some people say that OnlyOffice has the best Microsoft Office interoperability. If LibreOffice is not good enough, maybe give OnlyOffice a try.
