A stylus with both pressure sensitivity and palm rejection would be the best replacement to maintain the same level of functionality provided by the original stylus. Pressure sensitivity allows for variation in line thickness and opacity based on the amount of force applied, which is important for drawing and handwriting tasks. Palm rejection ensures that the tablet will not register accidental touches from the user's hand while writing or drawing with the stylus. Alternative options such as a basic capacitive stylus or an active stylus without these features would not provide the same experience as they lack either pressure sensitivity, palm rejection, or both.
