IspConfig for professional hosting?

[xciso]

Hi.
I am going to start a small hosting service.
Is IspConfig good for professional hosting?

I am also looking on DirectAdmin.

DirectAdmin looks good, but the good with ispconfig is that it is free.
Is anyone here working with ispconfig on a professional hosting?

What would u use?
1. IspConfig
2. DirectAdmin

Sorry for my english
