'Good enough' really depends what you need it for. I understand that LO has more people working on it than AOO, so I wouldn't expect the latter to catch up unless there's some big shift in the landscape.
StarOffice was already good enough over a decade ago for me to buy it. Back then, WordPerfect was still around. Today, OpenOffice and LibreOffice are the last of their kind but the latter has a much quicker development pace. They could just box it up and ship it like OpenBSD does, 10/10 would buy again regardless of how they call it.
