The SwitchBot Contact Sensor. Beyond door and window contact it also picks up motion and light in the same unit, which the Aqara Door and Window Sensor does not. Note that with Alexa only the SwitchBot's open/close function is exposed, with motion and light staying in its own app.

The Aqara Door and Window Sensor supports Apple HomeKit (and Matter) through an Aqara hub. The SwitchBot Contact Sensor has no native HomeKit, and its Matter, Alexa and Google support requires a SwitchBot Hub.
