Black Sabbath/Heaven and Hell

Black sabbath is aww i hate to write so mutch http://en.wikipedia.org/wiki/Black_Sabbath anyway, people are discusing about who is better R.J Dio or Ozzy, i mean both are good, but ozzy is better entertainer and he is crazy thats what makes him so popular and Dio well Dio he had great voice and his lirycs were awesome his whole character was so positiv and friendly and if someone says ozzy sings better then dio, he dont have idea about what music is and should stop to listen to metal/rock or any other genre...

Talent wise I have to go with RJD..But I love both...
