Microsoft Office 2008
Your most familiar option when selecting a new office suite for your new Mac will probably be Microsoft Office 2008. When it comes down to it, Microsoft Office is still the most popular office productivity suite and its document formats are widely used and accepted among almost all companies, organizations and universities.

iWork
If you switched to a Mac for all things Apple, then iWork will probably be the platform for you. It comes with 3 applications Pages (word processor), Keynote (presentations) and Numbers (spreadsheets).

OpenOffice
OpenOffice is a free open source application that is available for all operating system platforms. It offers compatibility for opening and saving all popular Microsoft formats. OpenOffice has a handy autocomplete feature that recognize commonly used words and completes the word for you. With a look and feel very similar to that of Microsoft Office, OpenOffice will be a quick transition for any current Microsoft Office users looking for a quick switch, and best of, OpenOffice is entirely FREE!

NeoOffice
NeoOffice is a port of OpenOffice made specifically for the Mac OSX platform. NeoOffice has integrated dozens of native OSX features, which makes it a great choice for Mac users (new and old). Some of the native OSX features found in NeoOffice are:

1. Media Browser
2. Native Floating Tool Window
3. Magnify and Swipe Trackpad Gestures
4. Menus available when no documents are open
5. Import images from scanners and cameras
6. Cmd + Clicking on the window titlebar
7. OSX Leopard grammar checking support

In terms of functionality, you’re not going to find much in Microsoft Office that isn’t offered in NeoOffice.

Summary
If you’re looking for familiarity and don’t mind forking out $349, Microsoft Office 2008 for Mac is probably going to be the best choice for you. Or if you love everything about Apple, and the simplicity of all things Mac, iWork is probably the platform you’d like to consider – with a price tag of only $79, it is very fairly priced and will get the job done for you. If you’re looking for a fully functioning office suite on a budget (or on no budget), your choices are simple – OpenOffice or NewOffice. I’ve chosen to go with NeoOffice due to the fact that it was ported from OpenOffice, and it builds upon native functions of Mac OSX.

My choice – NeoOffice.
