From Blabbermouth:
"Yeah, I did admit that Bruce is a better singer for MAIDEN than me. I still do think that but only related only to the MAIDEN albums that were made after my first two initial MAIDEN classic albums. My feeling is that I could never have stamped my mark properly on the MAIDEN albums that came after 'Iron Maiden' and 'Killers' because Bruce's voice is much better suited to that material than my voice ever could be. However, that aside, I am not actually comparing our voices against each other either, as I feel as much as I could not sing Bruce's period of MAIDEN songs, Bruce definitely does not have and never did have the voice to replace me on the first two classic albums either.
"My voice is, and always will be, mega aggressive and that is what helped make those first two classic albums what they are. On the other hand, Bruce's high-pitched, and sometimes operatic voice, is what has helped give the later albums their different character. I will say this though: Bruce sounds incredible on many later MAIDEN tracks such as 'The Trooper', 'Number Of The Beast' and 'Two Minutes to Midnight' but lets face it without meaning to sound arrogant here, just saying what everyone knows when Bruce tries to emulate me on classics such as 'Remember Tomorrow', 'Running Free', 'Wrathchild', 'Killers' or anything from the first two MAIDEN albums, he just does not have the tools for the job as the aggression just isn't there. Your voice can often explain a lot about your background, and I think my voice shows the kind of rough, lower-class background I came from. Bruce's voice kind of gives an impression of a public schoolboy background."
