From my experience and opinion:
Webmin/Usermin/Virtualmin: good panel, not the best UI but doesn't mess up with your server
Kloxo: outdated with a nasty UI, you might want to look at Kloxo-MR which is an active fork of Kloxo
zPanel: stay away from it (security problems and bad 'community', read for example: http://www.reddit.com/r/netsec/comments/1ee0eg/zpanel_support_team_calls_forum_user_fucken/)
ISPConfig: solid panel, requires some manual work to get it working
VestaCP: love this panel, it has a clean structure and doesn't mess up with the server
Ajenti V: I've used the standard Ajenti package about a year ago and it was ok, Ajenti V looks interesting with support for nodejs which other panels don't provide
Open Panel: seems dead but it did the job when I tried it

Other panels I didn't tried:
Froxlor: requires some manual work to set it up
i-MSCP
EHCP
AlternC
CentOS Web Panel

You might also want to check TuxLite, it's a shell script that will help you manage a LAMP/LNMP stack with simple commands.

Any review of Webuzo ? They have a free version.

It's ok, I personally don't like it because you don't get much control over what you do, but it allows you to install wordpress and similar cms in one click.
If you know what softacouls is, webuzo it's pretty much the same thing. The downside is that it isn't a multi user panel.
Helpful and free support over skype.

Is it possible to add a domain to the "DNS" section and then also add that same domain to the "Websites" section to allow me to control the mxrecords of the domain while also using it for my websites? At least, that is how it appears vesta works to me.

Yes, vesta will setup a full web server with mail, dns and ftp access.
It's very flexible, you can choose to host the website and the dns on your server, while using google mail for your emails.
