There is no comparrison, i have been a drummer for close on thirty years. Clive Burr is without a shadow of a doubt a better drummer, he is tight, solid, great fills, fantastic feel for the quieter passages, and much more power in the overall sound of maiden. people go on about nicko being technically superior which isn't the case. Nicko is a one trick pony. Think about it! He always does a lot of fills to rest or break from the signature beat, on his live stuff he is very sloppy. if you listen to his fills most of them are basically the same, with one or two different beats here and there, his bass drum beat is nearly always the same, the off beat.His trick is always play the same on the bass drum as what his right hand is doing. POOR.....
