Voted for Tiger, but not really a fair question, Jack's career is over, where as, Tiger's career may just now be peaking. If one takes into consideration the accomplishments by the age of thirty and the caliber of competition that each had faced up until that time, I think hands down its Tiger.

The issue with the improvement of equipment is a valid one, however, golf courses are designed now to defend the long drive and the high spin wedges. If you watch older matches, courses were a lot shorter, fairways were a lot wider, and greens were ridicously slow. I think Arnold Palmer said it best, "Watch Tiger closely now, because there may never be another one like him."
