An active stylus is the best option for a graphic designer who needs precision and pressure sensitivity for digital artwork. Active styluses are powered and communicate with the device for additional functionality like pressure sensitivity, which is crucial for artists when they need to vary the width and opacity of lines based on the pressure applied. Capacitive styluses only mimic a finger touch and lack pressure sensitivity, while resistive styluses work on resistive touchscreens and also lack the sophisticated pressure sensitivity and precision required for detailed artwork.
