That's always been the way with Anthrax - Bush or Belladonna.
Usually it's by when you find out about them, I grew up with Joey as the front man, so you can guess which way my vote goes. But I get your attitude, what is interesting about the whole thing was Scott Ian's take. He has always been very vocal about his support of John and his vocal style, but he said in a recent interview that he was amazed at the sounds and how right it felt to have Joey back. He went on to say, "Even I get it wrong occasionally."
I grew up in the 80's with Joey as the front man as well. On my first summer back from college, my buddy Steve came over and pops in the newest Anthrax and it starts with "This is a journey into sound."
The Sound of White Noise was a perfect album. Potter's Field and Only were perfect songs. It was like Anthrax was reinvented itself.
