Have you used ms office? I've used both extensively and ms office is clearly and obviously superior in my opinion. Superior in usability, not in functionality (you can do everything with LO, it just takes more work).

I'm a huge FOSS proponent but the Ribbon design blows the LibreOffice design out of the water in terms of UX. I'm seriously more productive with MS Office and I've been using OO/LO for 4 years now!
