There are very few players I can't think of that can get to the basket and finish as effectively as Zion. What is he doing technique-wise that makes it look so easy? The moves leading up to the finish seem different than other players approach to driving, but I can't put my finger on it. Some of his finishes are spectacular, especially working through double teams, but most are very basic drives that just involve a single fake to get the defender moving one way, then slash to the hole.
The part I think is unique is that he pivots and jumps at the basket in both the vertically and horizontally direction, doing it very far and fast. I think he using every bit of extension coupled with his vertical. And adding to that, he is always looking for the rebound after his shot or a block, plus he has great touch and offensive IQ positioning his body making it all very unguardable.
He has great bend almost like a defensive end how they are able to get low and bend to turn the corner all while moving incredibly quick for that size. Then he explodes up and into anyone in the way. His size allows him to absorb that contact and continue up and forward and then his touch to get the ball softly to the rim. Then if his first shot misses his second bounce and hand strength is crazy so he is able to grab his own rebound and put it in.
