I see the same thing. When I use my finger, it seems pretty smooth and fluid. There are two modes for writing in Penultimate: coarse mode and fine mode. The fine mode is also called 'drift' mode where you pinch zoom to where you want to write then the touch screen 'pixels' or points have more resolution. This allows the stylus to write finer. Still, it tends to miss 'guess' as the stylus tip gets close to the surface and lay down somewhere where the tip isn't. But as I continue to write, it catches up. Bottom line, until Adonit fixes the oddities how the two interpret, I guess we eat the $$$
