Virtualmin is missing from the list. It's one of the most secure and popular but not exactly newbie friendly. Also I use Kloxo-MR which is pretty good.

I have tried  CentOS Web Panel  too. But it's too laggy and buggy. I asked about few bugged in their support forum which they decide to ignore. Nice interface though.

Wanted to add Virtualmin, unfortunaly I forgot it. Never use it myself.... As you say it's not newbie friendly, so for my purposes it isn't that useful.
