What is the best OS for CyberPanel

What is the best os for cyberpanel? Ubuntu 20.04?
I want the fastest experience

Cyberpanel appears to be developed for ubuntu first, with added support for other OS.

So, if you want things to be more tested, run ubuntu.

If you wanna don’t mind fixing yourself an occasional bug that may appear, use almalinux.

Not really. In fact, not long ago Cyberpanel only supported CentOS
