14 majors but still the greatest wrote:
Nicklaus did well for his era. He competed against about 10 other good players and a bunch of nobodies. Golf was still incredibly racist during his dominant years and there wasn't much competition from overseas.
The fields Tiger competed against are much, much stronger. Most of the guys Nicklaus played against couldn't quality for the secondary tour these days.
Nicklaus was sort of like a 4:30 miler competing in a weak state and winning a lot. Commendable but impossible to regard him as anything near the best.
This article really lays out the difference:-
https://www.usatoday.com/story/gameon/2013/04/15/tiger-woods-jack-nicklaus-comparison/2083049/Just points 1 & 2 are enough to put the Tiger argument to bed:-
1. Jack was second-best the most
Nicklaus finished second in 19 majors, and Woods has six runner-up results. Nicklaus had 48 top-three finishes at Slams, twice as many as Woods.
2. The competition
Overall, the current depth of fields and reach of international talent exceeds that in the days of Nicklaus. There are more talented golfers coming from more diverse locales, but very few of Woods' contemporaries have stepped up in majors. The two active players with more than three major titles – Phil Mickelson and Ernie Els – are rarely direct rivals for Woods. Nicklaus, on the other hand, played with Gary Player (nine majors), Tom Watson (eight), Arnold Palmer (seven), Lee Trevino (six) and Seve Ballesteros (five). While Nicklaus finished second more than 10 times to players on that list, Woods' runner-up finishes have been to one-hit wonders like Trevor Immelman, Zach Johnson, Rich Beem, Y.E. Yang and Michael Campbell. There have been few worthy adversaries.
Also incredibly compelling is their Augusta records. You just can't argue with those stats...
Tiger = Greatest hyped up by Nike golfer of all time.
Nicklaus = Greatest golfer of all time full stop.
