the next big OpenOffice release (4.0) is supposed to be quite good. Especially improvement to MS document formats compatibility. Since about summer last year the OpenOffice developers have worked on implement much code of Symphony (IBMs Openoffice-Fork). This will go into the 4.0 version.
The better compatibility is shown in their wiki: Documentation/Fidelity Improvement Since AOO341
Many bug fixes
Currently I'm using LibreOffice, but I might switch back to OpenOffice when 4.0 is released.
