Yep. If you want to offer paid shared web hosting then cPanel is a must. There won't be too many people who are willing to by shared hosting with a free control panel. Shared hosting industry is dominated by cPanel. Other panels like DirectAdmin or Pleaks give very little competition.

Direct Admin is also good, but it was used too much before. and it is still used, but not by many companies. I just like Directadmin because it is affordable.
