i've used abiword on my sister's pc and it seemed pretty nice (i have not yet used ooo). it had all of the basic word processing features and a decent dictionary/thesaurus. it also had some cool plug-ins that you could add, the most impressive was the image magik plug-in set that allowed you to perform preset transformations on images right from the contextual menu. it seemed to open plain text .doc files ok, but i don't know about the more complicated ones. for a 4 meg download it was very impressive.
