Love abiword, but OpenOffice is a better suite (though it is heavy)

For .doc: OpenOffice
For .odt: KOffice - FASTER

OpenOffice is too bloated for me.
Not to mention that integration with Gnome sucks.

I prefer KOffice, and when I'm working with my Gnome-based laptop, I prefer AbiWord + Gnumeric.

Open Office.org

That's really hard. I use KOffice most of the time on Linux (although sometimes I use OpenOffice.org), but OpenOffice.org when I have to use Windows. But since this is a Linux forum (and I use KOffice more than OpenOffice.org on Linux, and KOffice will probably get less votes then OpenOffice.org), I'll vote KOffice.

OpenOffice.Org, hands down, I mean, come on, there's even a "portable version" that'll run from a thumb drive on Windows so I can have my docs where ever I go in the format I prefer.

OpenOffice...

Koffice gets my vote this year because of the vast improvements in the suite. I still use OOo and like it very much, but Koffice is my preferred opensource office suite.

OO.o is so fat and bloated that it runs slow on my dual core Opteron w/2gigs of ram and a 10k Raptor. Also has run on 64bit systems for far too long (although I think if finally may?).

Koffice is not as feature complete but has progressed nicely. Also, why since when is "opening MS files" become a requirement for *nix software. Bah!! Just tell though MS weenies that if they want your help then not to send you stuff in a closed, proprietary format ;-P

I used to be exclusively an OOo user when it came to Linux, but after I upgraded to Slackware 11 from 10 (actually did a clean install) I decided to give Koffice a try before installing OOo, and I actually haven't missed OOo since. Koffice has been great and has done everything I ever needed OOo to do.

OpenOffice.org is by far the best.

I really need to be able to open different MS-Office documents (I really wish I didn't), and only OOo can do that well.

I also like AbiWord and KOffice.

I'd have to go with OpenOffice mainly because of the power of its Spreadsheet and word processor. Granted, the Database end of it leaves much to be desired. Also, the draw and presentation, is pretty easy to use and if you've got any experience with MSOffice, OpenOffice is exceptionally easy to use

Definately OpenOffice. Opens most things that you can throw at it, which is especially important in an MS dominated office environment.

I tried some of the other office suites but always seem to come back to Oo when I need to do labels (Oo has dozens of Avery templates), envelopes and other special printing jobs. Oo is a MAJOR resource hog, but maybe it's time to admit that while most Linux apps are more resource-efficient than comparable M$ apps that there is still a certain amount of resources a comprehensive office suite- or other major app- has to have to be useful. Rather than sacrificing capability at the altar of simplicity the Oo creators seem to have decided to make it as big as necessary to be useful by a wide range of users. Oo has my vote.

I prefer KOffice because it's much faster. But anyway I am often forced to use OpenOffice because all my aquaintances use M$ and Microsoft Word. I would like to see a better .doc files decoding in KOffice (or, even better, but more ambitious, that M$ implemented the use of OASIS).
