iron maiden vs judas priest

Priest from Sad Wings of Destiny to Screaming for Vengeance.
Maiden for the full body of work as a whole.
 
Maiden probably, but from 90-98 they put out some weak music. There was a gem here and there, like Tailgunner, Be quick, Afraid, Fear, Clansman, and Futureal. My God I hate it coming down to this, those two are my all time favorites.
 
I was never the biggest Priest fan but I have nothing but uber respect for them.

But it's Maiden for me.
