Choosing a control panel depends upon the Hosting plan you choose. Generally Plesk and DotNetPanel are offered along with Windows Hosting plans and cPanel with Linux Hosting plans. Different control panels have there own importance. But it is said that cPanel is a very user friendly control panel when compared to other control panels available in market. Its a very fast control panel and has a very simple user interface, so even a new user can use it easily.
4 main panel Helm,Cpanel, DirectAdmin, Plesk.
Each of these has their own set of advantages, and yes, disadvantages too. but one has consistently out performed the other control panels. The control panel software I speak of is Helm.
There are number of good upcoming panels and there are number of over-rated panel like plesk which I have always experienced to be very problematic yet it seems its has attained good publicity.
It all comes down to which panel and you and your clients prefer over others. There really is no best panel.
Cpanel and Plesk are widely preferred and used Hosting Control panel. My vote is for them you can use them.
