Hagen won lots of PGA titles that Jones didn't enter (nor the other top amateurs of the day), and never beat his illustrious rival at an Open championship (US or British). No question which of those two ranks higher. I'd also put Hogan above Snead, as although Sam won more in quantity, Hogan's almost total dominance in, again, the majors that mattered after coming back from his terrible injuries in 1949 eclipsed anything Snead did. Not maybe a candidate for number 3 but a definite top 5 shout for me would be Seve - not just for his 5 majors but the fact that he was the player who showed European golfers could win majors in the States against the very best like Nicklaus and Watson and opened the floodgates for Langer, Lyle, Faldo etc.
