Joshua has the better footwork, balance, hooks, uppercuts, combinations, parrying, blocking, jab is about equal(might give slight edge to wilder), better at cutting off the rung, better body puncher, better at fighting at a faster pace. Defense is about equal I would say.
Wilder on has the edge in stamina, athleticism, and power. Please, tell me if i'm wrong.
On AJ, I agree with all you said except the following:
1. Footwork: AJ does not have the better footwork. He is more fundamentally compact but that's not all there is not footwork. Wilder is more agile and moves better in and out than AJ. Wilder also pivots much better than AJ. .
2. Blocking: I cannot agree here. Neither can I disagree. The reason I say this is that AJ is rarely ever defending because he is the offensive fighter. AJ's offense is his defense most times. Also, like Wilder, he has been caught with some clean shots as well. So, I am not sure we can say that.
3. Better at cutting ring: No, he is not. They are at worst equal. AJ has constantly had trouble cutting off the ring. Just take a look at his last fight for evidence.
4. Fighting at faster pace: How can you even say this? What is the proof that AJ is better at this? There is not enough sample size to show this.
Now, on Wilder:
1. Better jab - it is not close unless you want to be in denial. AJ rarely uses his jab to destroy an opponent because he is looking to setup his combinations. Wilder utilizes his a lot more and a lot better.
2. Right hand: Wilder has the better right hand - power, direction and accuracy. I am not saying AJ's is not good. If I will rate, it is 9.5 for Wilder and 9 for AJ. So, it is close although in power, Wilder has a lot more power.
3. Movement - Wilder (though clumsy) moves better than AJ. This is in multiple directions and Wilder pivots extremely well. This is probably his most underrated skill.
4. Fighting on the back foot - Wilder is the best right now amongst the heavyweight. AJ is terrible at fighting on the back foot. If you don't believe me, take a look at Takam, Wlad, etc. They all show this huge flaw he has. He almost seems clueless fighting on the back foot.
5. Punching while moving - AJ is average again at this. Wilder is better. AJ likes to corner people because he is trying to throw combinations. But combinations only matter when you have a stationary target or an oppoent who is hurt.
6. Speed - perhaps what makes punches more dangerous and effective. Speed kills. Wilder is faster than AJ. As is said, it is the punches that you don't see that hurts the most. Now, please note that I am not saying AJ is not fast. He is fast, but not as fast as Wilder. AJ, though, throws great and fast combinations.
I think you spoke about the rest, i.e., stamina (that's a beatdown there although it might not matter), power (I think we agree here), athleticism.
Now on the fighting on the front foot, I think I will give AJ a 9.5 and Wilder a 9. AJ is more aggressive and willing to take a shot to land a shot. Wilder seems more calculated before jumping in. AJ fights better in range 2 and delves into range 1 (up close). Wilder prefers to fight in range 3 but could transition almost immediately to 1 (skipping 2) or to 2.
Look bro, I know we are on different sides of the fence on this. My only ask is for them to fight. Somebody will win. I think Wilder, you think AJ. Let's see.
