Whitehat Security  http://www.whitehatsec.com/home/index.html 
Zion Security (Belgium)  http://www.zionsecurity.com/ 
I haven't rank them and I believe it would be difficult to do so.  Aspect has been recommended a few times, NGS Software is owned by David Litchfield who I've known since the mid-90's.  Each vendor probably employs a well-respected webapp pentester, and I'm sure each engagement will have a different experience.
I believe a pentester is an important addition to a security toolkit.
