@matigo Once you adapt to its quirks, it's hard to beat for the kind of stuff I do. I haven't paid close enough attention to tell the difference between OpenOffice and LibreOffice; they both write to the same standard and open the same docs, so they're interchangeable to me.
I can tell you that I have .sxw files from 15-17 years ago that can still be opened (some of which I've converted to .odt files), and that both OO and LO can open corrupted .doc files that Word chokes on (though I've long since converted all my legacy .doc files to .odt as a precaution).
I'm mainly a word processor user, so I can't speak to the advantages/disadvantages of the other parts of the OO/LO suites.
