Apple offers four different Apple Pencil models and which Apple Pencil you should buy is determined by which iPad model you have.
All the iPad models are compatible with at least one Apple Pencil model, while some support more than one.
The first-generation Apple Pencil is only compatible with Lightning connector iPads and not with second-generation Apple Pencil or the Apple Pencil with USB-C.
The Apple Pencil with USB-C is the best choice for most users, as it is compatible with a wide range of models and has a more modern design.
Choosing between the second-generation Apple Pencil or Apple Pencil Pro and the Apple Pencil with USB-C, the second-generation and Pro models are a better choice on account of their superior feature set and easy pairing and charging experience.
The Apple Pencil with USB-C is still a great option at a more affordable price point for those who have basic needs for activities like handwriting notes and marking up documents.
All four Apple Pencil models feature pixel-perfect precision, low latency, and tilt sensitivity.
Design, pairing and charging methods, pressure sensitivity capabilities, and more feature differences exist between the different Apple Pencil models.
The first-generation Apple Pencil is $99, the Apple Pencil with USB-C is $79, second-generation Apple Pencil is $129 and the Apple Pencil Pro is $129.
Apple Pencil provides compatibility not just limited to iPads but also to other iPad accessories.
