First of all, I think this issue is controversial because Harden and Curry are two players in different positions and it's hard to compare them directly. However, if you want to think about it in terms of data and achievements, I can give some perspectives.
Curry is one of the greatest three-pointers in NBA history, and his shooting skills and on-court performance are amazing. He has excellent shooting ability, fast shooting speed, and extremely high shooting percentage, which makes him very capable of scoring. In addition, Curry is also an excellent passer and defender, and he also has a very high basketball IQ.
Harden, on the other hand, is a very well-rounded player, who is excellent on both the offensive and defensive ends. He has excellent scoring ability and passing ability, as well as a high basketball IQ and leadership. He was very consistent in the game and was able to step up in key moments and help the team win.
In terms of stats and achievements, both Curry and Harden are very good players. Curry has a higher accomplishment in scoring and three-point shooting, while Harden is better in terms of all-round and leadership. So I think it's hard to simply say who's stronger, it depends on what you value more about the player.
Finally, I would like to say that basketball is a team sport, and individual performance is inseparable from the support of the whole team. Both Curry and Harden need the support of their teammates and coaches to perform at their best. Therefore, we should respect the efforts and contributions of each player, rather than simply comparing and judging them.
