I think Bishop case was one very similar to the likes of Waqar. Prior to his much publicised back injuries, Bishop was very much on tap to be not just th greatest WI paceman but among the greatest of all time. Such was his talent. I have no doubt that pre injury Bishop was better than Gillespie but post injury probably a lil worse.Gillespie was as good a bowler as Bishop, or very close.Both careers sadly marred by injuries too. Bishop especially
Edit: not that that's the point, I'm just saying.
I don't think you could reasonably say australia's pace bowling ever had the depth of the WI.
Overall I would take Bishop though. But Jason Gillespie was no doubt one hell of a bowler and served his country with distinction
