I assume your second link should be [www.instructables.com]
I think it only looks more jerky because the pointer is much bigger. A typical stepper motor has 1.8 deg step, they both look about the same angle. I would suggest trying that instructable. If you want to get near 1:1, you need to find an encoder with more steps, they tend to be more expensive.
