I've used ISPConfig 2 in the past, but switched to ISPCP as it's customization was kind of easy, as in changing images and specific text, etc...

Now that I'm gathering more systems and want to have a permanent setup and actually start to sell hosting, I want to know how simple it is to implement more servers (physical boxes) to a current setup. Also, I'm curious about main features over ISPConfig 2 AND ISPCP (if known).

Why would ISPConfig 3 benefit me over another setup of the same? Finally, I know Debian is basically one of the best server distros out there, BUT can Ubuntu Server be just the same with ISPConfig?

I've got to do my research before I set foot in one permanent solution.
