Digital :

Analogue :

Look the same, but perform way different.

The Digital is promoted "as Servo like".

The analogue talks a lot about "the driven motors can run with smaller noise, lower heating, smoother movement and have better performances at higher speed"
Which tells me, they still have a choppy jittery feel at low speeds, but better than most on the market.

Steve, loving your (Datsun 180B) project -(worm gear stuff).
Engineering greatness!

My head (mind) is somewhat in the Datsun 180B, but my heart is in the Ferrari. I have the hands to design to build that 180B, but my heart won't let me...haha.
The Datsun 180B will be in the gearing and mounting.
