5693 ● 3 ● 48 ● 41 I usually give OSX users a copy of LibreOffice if they ask for something that can open all of the Word/Excel files that people send them (which is their primary use case :-). Speaking more generally, I think that LibreOffice provides one of the best FLOSS 'office suite' tools, and has a solid community of both paid contributors and volunteers.
One issue I've had with NeoOffice is that I couldn't find an open/free support forum. In the past few months I've tried to help out a handful of people who were having problems with NeoOffice, but because you must have a paid support contract to use the official NeoOffice forums (and because I don't regularly use OSX), I saw no reason for me to pay them $100 a year just so that I could help triage someone else's problem.
There's a comparison of NeoOffice, OpenOffice.org, and LibreOffice on the NeoOffice site, however it hasn't been updated in 6 months and probably isn't including all of the features that LibreOffice has added since then:

In terms of releases, the latest stable release of LO was 5 days ago, while the latest stable release of NeoOffice was over 5 months ago. I believe that LibreOffice has a number of new features and feature-improvements that are not present in NeoOffice.
If I were using a Mac, I'd use LibreOffice.
In any case, good luck with whatever software you choose!
