the defacto standard in hosting panels is cPanel - it's the control panel most hosting customers are familiar with and you can't go wrong offering it as a panel to your web hosting clients.

most powerful control panel easy to use many plugins and easy to manage files emails & database

Using cPanel as a Webhosting control panel is good for everyone. with Cpanel I can control FTP accounts, email accounts, subdomain and domains, MySQL database with PHPMyAdmin, also the file manager of Cpanel. Moreover installing SSL/TLS is very easy by Cpanel and with its built-in control management system. Another thing I like in Cpanel is a website builder and different platform easy project setups like Nodejs app and python app easy intregration. In a sentence, you will get what you needed in a Linux server platform to control your server system. I hope one day there will be support for the ASP .Net core program in Cpanel. Cpanel is easy to use and easy to maintain for a new user and a semi-technical user who has little knowledge of hosting.
