I second NeoOffice. I changed from OpenOffice to NeoOffice after X11 became corrupt and it took forever for me to find someone who understood that it was a corrupt X11 and not me that was at fault. Although I now have a healthy X11 installed on my mac, I decided that OpenOffice.org was only a great app if used on my PC alone ....
NeoOffice 2.1 has just been released BTW.
