My own server has cpanel but I have Plesk on both Windows and Linux for hosting, cpanel for hosting, lxadmin for hosting, servercp, directadmin as well

LXAdmin is a very nice panel, user friendly and gives you alot of control features over account

Cpanel has become very buggy since new release so in my opinion barely worth the money of licensing any more, but is still most popular among clients cause is what they know

Plesk is decent all around

Direct Admin is kind of limited but a nice panel anyway

ServerCP is nice cheap panel, only thing I dont like about it is is a nightmare to add modrewrite into the config without breaking theor DSM system
