Federer vs Nadal, who is better?

Personally, I feel that Federer is more powerful. From the early stage, Nadal was obviously better than Federer before the age of 22. However, Nadal was depressed at the age of 29 and 30, Federer was depressed at the age of 32, and Nadal was hot at the age of 32, ranking first in the world for a long time. Nadal suffered frequent injuries in his career. Of course, the injury was not serious, which made Nadal miss many games, such as the atp year-end finals. In fact, Nadal has not won the atp year-end finals so far, which has greatly affected Nadal's career performance. Now Federer is the best player in men's professional tennis, and Nadal is one of the top players in history in terms of performance, but in terms of performance and stability, Federer naturally won. As for the record of their fights, including Fernando Mu's, Federer is naturally not as good as Nadal, but I feel that Federer's career score is better and more perfect than Nadal's.
