Novell vs SMS. vs Altiris The victor is?

Hello all, I am looking at proposals for each as a management solution for us. Does anyone have any opinions/reasons why they prefer one over the other? Zenworks I have *some* experience with and find it to be an excellent solution. I am hearing excellent things about using Altiris and lots of drawbacks to using SMS. What do you folks think? Just broadening my base of knowledge 🙂
