Finally cast my vote, Ponting. Looking at the votes cast 46 - 28 is closer than I thought it would be, tbh.
Ponting has fallen off and Kallis (like Tendulkar) seems to have found a second wind at the tail end of his career. But, I think, Ponting has done more over the course of his career to be, in my mind, comfortably ahead. Kallis would have to do one hell of a lot over the couple of years remaining of his career to catch up to Ponting, let alone surpass him. I think it beyond him. More to the point, statistics and achievements aside, Ponting is just the better batsman, IMO.
