My thoughts for what they are worth
1) The comparison site is, like others, only showing the positives, "we're better than Office in doing this". It does not show what NeoOffice can't do. Unfortunately most of their positives don't relate to most users.
2) With MS Office (Windows Version, don't use it on my Mac) I can do a custom install. I only need a Word Processor for home use. With MS Office I get that option. With Open Office/NeoOffice, it's all or nothing. It's the whole Office Suite or nothing
3) On Linux, OO is a resource hog
4) NeoOffice is Java, Ugghhh
Me, I'll stick with AbiWord unless some future employer decides that I must use MS Office for work and decides to buy it for me.
