The two technologies are actually quite different.
Ninjago uses commercial-grade Leap Motion technology and you can buy it on
Amazon for under $200.
It's limited to simple gestures and mostly tracks the speed and direction of your hand movement and shoots your virtual fireballs accordingly. Your aiming is limited and it's mostly about moving your hands back and forth as quickly as possible to kill the lego people.
On the other hand, Web Slingers is using Vision AI to track your entire upper body, arms, shoulders, head, and face movements with a camera using the latest Deep Learning vision technology. Something similar to this but far more sophisticated:

It can track your full upper body and react accordingly with much better precision and no need for sensors or controllers. Unlike Ninjago where you are just swiping your hands at 100mph hoping to hit something, you'll be able to point your arms in the direction you want to shoot and it will shoot that direction in a 3D space. It even looks like you can reach out and touch objects in the 3D space.
When I look at this portion of the Tom Holland video:

It seems as if he is using his hands (down to his individual fingers) to weave around a web.
Here are snippets from various articles I've found online:

I've sat here for months and kept quiet about this ride being a Ninjago clone. It is a bit of an insult to the hard work being done in the vision AI industry (which I work in) where I get to work with the latest tech from the likes of Intel and Nvidia and I think you will be far more surprised at the level of tech on this attraction in comparison to commercial-grade Ninjago.
If you want more details on how the ride plays out, how to gain points and work with your teammates, the Marvel article I posted above goes into that detail, but for those who don't have the time, here's another important snippet:
Can you pull doors off of containers or grab onto objects with your hands and move them around in Ninjago? No.
