I have Word, Pages and I have been using NeoOffice since my first MacBook, back in 2006.
It is an unbelievably good alternative to the others. Word is the best by far, in my point of view, but there are two features that I keep using Pages for - full screen view and the templates.
If you really needed Word or Pages, you would already know by now.
Get NeoOffice and enjoy it - spend the money on something that really makes your computing effective.
