+1. it is [practically drop-in compatible](https://nrf24.github.io/pyRF24/#migrating-to-pyrf24)
+2. easier to install or get updates with popular package managers like pip

+4. includes wrappers for RF24, RF24Network, RF24Mesh libraries
+5. includes a new [fake BLE implementation](https://nrf24.github.io/pyRF24/ble_api.html)
+6. has its own [dedicated documentation](https://nRF24.github.io/pyRF24)
+7. is compatible with python's builtin `help()`
+8. includes typing stub files for type checking tools like mypy
