The Leap Motion still does hand tracking better than MediaPipe, and it's still the best hand tracker I know of (besides larger devices like the Oculus Quest).

We've got an open source library for mobile hand-object input [https://portalble.cs.brown.edu/], and the version with Leap Motion is really nice, but doesn't directly work with a phone (we had to pipe data through a compute stick to make it work).

I'd love to see MediaPipe Hands match LeapMotion precision some day, but I'm not even sure if it's possible. A real depth sensor goes a long way.
