They are non-contacting sensors, so less susceptible to mechanical damage. They can be easier to coordinate with hard stop protection also. However, they do require repeatable clearance from sensor to target at the desired switch point, so their function will change if the arm or frame is distorted.
Generally, a stronger target magnet makes the Hall sensor less susceptible to switch point shifting when clearances change slightly. Sensor manufacturers usually provide details (sensitivity curves, operate/release magnetic field levels, etc.) in their data sheets and application notes.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
