All things considered, Apple Pencil remains the best-in-class stylus for Procreate in 2021. The Apple Pencil was developed with the iPad in mind. Thus, the sensitivity and the feel of the stylus is in a league of its own when it comes to drawing in Procreate. If you want to make the most out of all the tools Procreate offers, I would highly suggest investing in an Apple Pencil.
