None of those vocalists are in my top ten though Rob and Bas both do kick ass and are equal in my ears. Bas is probably technically a little better, but Rob has a lot more material. Just to be different I voted for Bas. I prefer Ronnie Dio, Tony Martin, Russell Allen, Mike Howe, Andy Kuntz, Urban Breed, Udo, Ray Alder, Chity Lanka, Geoff Tate and Jon Oliva etc.
