I have cpanel on my personal server, main one anyway but there are others that are good and some for a lot less price.
ServerCP, PLesk, Direct Admin is the other 3 worth mentioning.
Helm for Windows isnt too bad but I dont do alot with it since I have never been one to push Windows servers.
Is all a matter of prefernce I guess.
The one thing I dont like about ServerCP, bout the only thing worth mentioning is that Mod Rewrite isnt packaged in the panel, you have to manually install the mod and try not to break the system which is a bit tricky
