Daniel, as you know I quite agree with your choices. There should have been a rat(t) sneaking around somewhere on the Ratt cover though...

Here are my top 10/worst 10 then....

BEST:
Van Halen - s/t (simple and very much rock'n roll)
Motley Crue - Theatre of Pain (I'm surprised nobody used this idea before)
Kiss - Destroyer
Manowar - Kings of Metal
Queensryche - Rage for Order
Black Sabbath - Live eviL
Ratt - Invasion of Your Privacy
Scorpions - Love at First Sting (I'm a fan of Helmut Newton though...)
House of Lords - Demons Down (the CD longbox version)
Van Halen - 1984

WORST:
Lizzy Borden - Terror Rising
Fates Warning - Night on Bröcken (must have been made by 3 year old...)
Ozzy Osbourne - Talk of the Devil
WASP - The Last Command (the back cover is a cool ripoff of VH s/t though...)
Kiss - Carnival of Souls
Heavens Edge - Some Other Place Some Other Time (US version)
Black Sabbath - Forbidden
Manowar - Into Glory Ride
Slaughter - The Wild Life
Rush - s/t
