I myself have found AbiWord to be quite capable and in many instances more compatible with Microsoft Office in DOC file input/output. That's not to say that Open Office Writer is not good, but that the documents I have tried it with just did not look right in Office 2003, but were fine when exported from AbiWord.
I also find I like the online office suites including Google, but also to include Zoho, ajax13, and ThinkFree. I only wish they supported more formats for import and export. If they supported a few more formats like WPD (Word Perfect Document) they would be even better.
