All three bands had their moments. Who's better?
Ok could angus young play like eddie van halen? Probably could if he practiced and that was his aim. But he's a blues guy,and is the best at what he does.
Could Alex play like Ed? Probably. But he's a prog rock guy and is a monster .
Could Geddy play like Cliff Williams? He technically would run circles around the guy. His voice is what it is. I have never had a problem with it. Geddy and cliff smash on Michael Anthony but Mike would drink them out of the building.
The point being is are we talking technical ability,tone,presence,innovation? Best drummer? It ain't Alex or Phil Rudd.
But Rudd played in the pocket and AVH is great at what he does.

Here's my rating.
Technically -Rush
Flash and stage Presence-VH
Innovation-Eddie
Tone-AC/DC all the way
Ability- They all are better than any of us


Bon Scott for best frontman,Peart on drums,Angus on lead ,Eddie on lead,Geddy on bass,and that group would all kill each other during band practice
