I am getting headache trying to get my head around which hosting platform suit's what I need.

The major platforms, as I understand include:

CPanel, Plesh, Cobalt RaQ and Ensim.

BUT, which supports this in a standard package:

a. End-user account management (I know CPanel does not)
b. APOP/SSL email
c. WebMail system

What platform, in general, do people prefer the most (on both a hosting management and end-user level)?
