To be honest I am not sure as Dunstall was not the best forward of his era, while Buddy was of is, and Buddy is in an era where it is a lot harder for key forwards to kick goals, not just because teams no longer focus on kicking to their key forward as much, but also scores in general are lower and zones prevent key forwards kicking bags so Buddy's 918 goals or whatever it is so far is probably worth more than Dunstall's 1250.
Not to mention if Buddy was more ambition than raw talent like Dunstall was, hed have more premierships than Dunstall right now
