Strongly disagree! Way harder to achieve number one than to win a slam! 50 slam winners since early 70's in male tennis only 26 number ones. Not even close. It took Wilander 7 slam wins to achieve number 1. I don't care what the experts say, it's just facts, number 1 is harder to achieve than slams. Joker will have over 400 weeks at number one. No one will be even close. Even now he has over 115 more weeks and counting at number 1 than Nadal. Right now Joker is greater than Nadal, 115 more weeks at number one than Nadal. Plus Nadal has a huge blemish on his record. He's never won the year end championship. His winning percentage at that tournament is a pitiful 56%. Winning slams is tough a true test of endurance, but let's face it you only play 2 rarely 3 top 8 opponents. The year end championship every match is against the best of the best! As much as I like Nadal and hate Joker, Joker is just better, even though he has two less slams. His 115 more weeks at number 1 and his 5 year end championships far exceeds Nadal's two more slams!
You can disagree all you want, but to say the debate is over is just ridiculous.
