Which Door/ Windows sensor, Xiaomi Mija or Aqara ZigBee or Bluetooth

Is it better to use ZigBee or Bluetooth door windows contacts/sensors?

I’m currently using a Raspberry Pi setup with a ZIGBEE 3.0 USB DONGLE PLUS usb device to control ZigBee devices, the Pi also has Bluetooth and I have a Xiaomi ZigBee/Bluetooth Mesh hub as well.

Which would be better to us, a ZigBee or Bluetooth sensor?
