ispCP vs cPanel

[gnif]

ispCP uses your systems packages where cPanel compiles its own versions.
cPanel does not use standard system locations for applications.
cPanel does not work with Debian (believe me, I have tried)
cPanel is expensive, ispCP is free.
ispCP gets it's bugs fixed.
cPanel supports SSL out of the box, ispCP doesn't (I am fixing this )

There is more, but I cant think of any at the moment.
