Tiger is the second greatest major winner of all time, and the second greatest tournament winner of all time. He has a very good chance of being the winningest golfer ever, and a punchers chance of being the best major winner ever. His winning % is double that of any other golfer. Ever.
If majors are all that matter, Jack is the greatest. If wins are all that matter, Snead. But Tiger is #1 in win %, and #2 in majors and total victories. And he's not done, in fact he's currently the best golfer in the world by a large margin after dropping out of the top 50 a few years back. He's got the most worldwide wins this year, most money this year.
He's not done. He's more than competitive. Jack is probably out of the woods, but that's far from clear right now. These are facts. Not insults.
