Who faced tougher competition during his prime between Jimmy Connors and Bjorn Borg?

Question

Yes, they were of the same era, but there is still a four year difference. Ken Rosewall, for example, was never a threat to Borg like he was to Connors.

Answer 1

I think they both faced equally tough competition.  Connors played a longer career.  So he had to play a lot more players in the mid to late 80s :)

Answer 2

well borg sort of slowly left the scene when mcenroe came along.
