The open alternatives for the Nordic NRF5x are not at the same quality level as the Softdevice: - the idle power consumption is noticeably higher, there are open bugs for more than 1 year about that - They are not validated by the Bluetooth consortium. You're gonna need to get your own certification to claim product supports BLE. If you're building a commercial BLE product - my advice: go with Softdevice.
