I do not like MO and OOo (Microsoft Office, OpenOffice.org).
Is there any other VERY good free office for Windows/Mac/Linux?

GNOME Office (wikipedia) is also available for Linux. It includes:
...as well as other utilities. Some of these are available for Windows as well.
Google Docs is a web-based office suite. It does a number of things very well while in other ways lagging behind application-based office suites.
There's the K-Office suite for Linux, KDE
Or you can use an online office - google has it
AbiWord is a multi platform application, reads many standard document types (OpenOffice, MS Word, WordPerfect, RTF, HTML...) and has a good layout capabilities. As the program is very small, it requires very little resources and can be used on even older machines. It is extendable via plugins.

There's also SSuite Office - The Fifth Element with an innovative interface.
Another office suite light on resources is SoftMaker Office 2006 for Windows.
There's also the ZOHO online office suite.
Try NeoOffice as an alternative to OpenOffice. It's based on OpenOffice though, so I'm not sure if this fixes any issues you have with OOo. But since you don't specify what they are, it's hard to tell.
