Iron Maiden 1000000 times. I truly believe Metallica is the most overrated band in the world!!! No match between Maiden and Metallica....not even the slightest.
I preferred the Paul Di'Anno version of Iron Maiden but that's just me but between both bands Iron Maiden. I liked Paul fronting Iron Maiden cos he brought a 'punk edge' and contrasted well on the first album with the long haired Steve, Dave, Dennis & Clive and Adrian on the 2nd album Killers. E-Z
