Sonoff RF Bridge. Strategies for receiving data

I’m confused, is method 1 or 2 still preferred?

I am just configuring the device in the configuration.yaml, like this (working perfectly for 5 Govee leak sensors):

binary_sensor:
  - platform: mqtt
    name: "Water Heater Leak Detector"
    unique_id: "binary_sensor.water_heater_leak_detector"
    payload_on: "A123FB"
    payload_off: "A123FA"
    device_class: moisture
    state_topic: "tele/tasmota_XXXXXX/RESULT"
    value_template: "{{ value_json.RfReceived.Data }}"
    availability_topic: "tele/tasmota_XXXXXX/LWT"
    payload_available: "Online"
    payload_not_available: "Offline"

This seems extremely easy, scalable, and requires zero scripting.
Big thanks to @kosherPowerhaus for the tip.
