I prefer King Diamond in Mercyful Fate. He has a cool voice, but to be honest, I would be very embarrased to have someone overhear me listening to the King. Its a little over the top.
Lizzy Borden was a C level, maybe B level metal band. However, I've always been a big fan and Lizzy is one band that I can say has never released a poor disc. Great band.
Both are cheesy, but Lizzy gets my vote by far.
