Seriously, these two albums are like two of my kids. I've listened to both SO many times over the years and I have to say that both are/were VERY influential in forming my musical tastes in my younger day. For me, both albums would score 100 out of 100.I adore both of these albums. I've long said that BiB is one of the top5 greatest albums of all time. And I stick by it. Screaming for Vengeance is outstanding from the first notes of The Hellion to the final screams on Devil's Child.
Hard to choose one over the other. I'll really have to think about it.
