Do you use cPanel? - I guess the answer you are going to receive most is "yes". It is using widely and most people just love to see it in their host. The biggest advantages of cPanel are - it is simple to use, good docs and community support, their support team is awesome, so many add-ons available, outsourced support is relately cheap, regualr updates, etc . So is it worth ? That depends on for what purpose you are going to use it or how confortable you will be dealing with server commandline and other such utlities. If you are beginner and not in a mood to learn more - you should go for cPanel I suggest. If you have little advanced knolwedge, you may go with Plesk as well as it has some wonderful tools as well. There are other wonderful free / cheap solutions like directadmin, interworx, vestacp, centos panel, etc...but its all about how fast you can adapt their working and your hosting env.
