Jimmy, Zaheer & even Gul, all of 'em are of the same rank, I reckon.
You can use that argument a number of ways though. You could argue it's harder for Zaheer since he has no support so all batsmen have to do is see him off and then they can make hay vs the lesser bowlers. It's the old Richard Hadlee vs Malcolm Marshall argument or Murali vs Warne. One in a team of stars, the other the only star in their team.
Please tell me you were joking, about the Gul part that is.
Zaheer probably the better batsman though..
