OpenOffice vs. NeoOffice for Mac

If you own a Mac, are you running Microsoft Office 2008? You have some free options if you don't want to run any Microsoft applications. Two of the most popular alternatives to Microsoft Office are:

• OpenOffice
• NeoOffice

So which is better? Which do you like to use? I've loaded both on my wife's MacBook Pro and I'm waiting to see which one she likes better. Which application do you use the most? Microsoft Word, Excel, PowerPoint, or Outlook? For me, I'd have to say that it's Word. It seems like I'm always working on a Word document.
