I really wish Koffice would stop resetting my mime types without my permission. It is in strong danger of being uninstalled if this continues.

open office 3 is best one

For my needs I prefer abiword, gnumeric and epdfview (so I guess it is gnome office)

Using OpenOffice is a no-brainer but I actually use its forked dev OxygenOffice. Hugely compatible with the MS junk that's thrown at it.

I prefer Koffice

Definitely OpenOffice.

Openoffice is good and every release it is really doing fine.

I use all of them , sometime for fast loading i use abiword , also for weird stuff openoffice

I've used openoffice.org mostly, but I just switched to the Novell "fork" ("branch?") of 3.0 and it's the best yet.

my favourite is openoffice. but there are as always some minor compatibility problems..

While it's not a suite Abiword I feel deserves a mention here. As a WP if you don't have to worry about M$ office connectivity it is the best I feel. Not so great at importing/exporting M$ word files though.

OpenOffice3
 

OpenOffice3 is great. My wish is that Sun Microsystems keeps working and support the community of O_O developers. In a word keep the project's sources open.

check the link
 

Check the link I posted above. Novell contributes a great chunk to oo, and many developers claim Sun is mismanaging the project, sort of treating open source as if proprietary.

The Novell 'fork' contains a lot of improvements Sun wouldn't incorporate for whatever reason. Some because it doesn't fit their "vision," others due to plain old inertia.

I tried the version I linked and it's obviously better than the Sun offering. In fact it handles Microsoft office docs better, the 'compatibility issues' mentioned above (very true) were not apparent.

If you don't have an rpm based distro, search for "Novell GO office" and get the source. It's worth it.
