Over the years Climo has buried more clutch putts than anyone else. Think about the fact that for almost two decades KC has been the top player/putter with names like Rico, Todd, Shultz, Hammock (this guy needs to be on the list of sick putters), Russell, Tannock, Feldberg popping up and dropping off of Climo's radar of competition. It's very interesting to see that KC has maintained such dominance for so long. NO ONE else has been at the top and stayed on the top for as long as Ken Climo. Hands down best putter / player now and of all time. I don't see how you can argue that.
As far as women players, I really think that Angela Tschiggfrie stands out in my mind as putting goes, could be because I have seen alot of video of her hitting puts (my wife, Kendra, taught herself to putt by watching Angela and Kendra is a better putter than I am...that's not sayin much though) Of course, I know Val Jenkins is an amazing putter too...I think she actually won the world's putting contest this year didn't she?
Feldberg is the best since I started playing in 2005 but several people have told me that Cam Todd was an unbelievable putter. I think only Climo and Todd have signature putters on the market but I maybe wrong.
