not even close
Overall it is not even close. No-one who has not won either the US Open or The Open at some point in their career is even on the starting point of being a great.
I would make Tiger the favourite on any British Open circuit and a strong favourite over Phil at that. I would have Tiger as fave at the Masters, he putted poorly this time out and made the top 3. Had Mickelson played to the same relative standard 20th would have been more like it.
The US Open on a tight track I would perhaps say is 50-50 as Tiger needs straighter tee shots than he has been hitting. Ditto the USPGA if the track is tight. But if the USPGA is on a more open course I would say Tiger is still the strong fave.
