This is a tough assignment. There is a book "Australian Top 100 & First XI" - The authors placed players in eras and then compared them to one another. The problem I had was when they compared Bradman's contemporaries to him. He was so far in front, in the end, and not surprisingly the batsmen of his era struggled to make the final all time team. I thought at the time they should have just accepted Bradman as an anomaly and removed him from the comparison.
