You are not alone, and thank you for articulating this better than I could. The handwriting experience is the reason I return to Notability for any significant writing despite its performance problems. I've yet to find an app that reaches the same level of handwriting fidelity.
I really hope the good people at Muse make this a priority. That, and search.
