G.O.A.T.
The pro tour in the 60s seems to be mainly made up the aging remnants of the great 50's pro tour plus some less talented players filling the gaps. The 50's pro ranks seem much more impressive to me.
I wouldn't quite put it that way since Gonzalez was still pretty much in his prime in the early 1960's in winning another tour in 1960 by an awesome score o 49 to 8! He defeated Rosewall by a score of 15 to 4 on that tour!
Gonzalez won a second oddly set up tour in 1961 over Gimeno, Hoad, Olmedo and Buchholz and MacKay by a total score of 33 to 14 in a round robin portion. Gimeno was second with a record of 27 to 20. Hoad was third at 24-23, Mackay was 22-25, Olmedo was 18-29 and Buchholz last at 16-31.
There was a playoff (with Sedgman subbing) with Gonzalez winning with a record of 21-7 over Gimeno who was 7-21. Sedgman subbed for Hoad (I believe) and defeated MacKay for third place. So Gonzalez was World Champion against in both 1960 and 1961.
Gonzalez retired in 1962 and returned in 1964.
However adding Laver in 1963 in the Pro Ranks wasn't exactly bad. It was strong but imo not as strong as the 1950's.
