LPWAN in IoT

We heard that all roads lead to Rome. In LPWAN unfortunately the roads lead in different directions: one path leads to Sigfox; The next way leads to LoRa and further divides into LoRaWAN and other directions; another path leads to LTE-M with a junction to NB-LTE; yet another way leads to Weightless where the road forks to Weightless-N, Weightless-P and Weightless-W.
It is not so easy to take the right path. With the press release of Huawei and Deutsche Telekom the LPWAN map comes even more confusing:

Deutsche Telekom and Huawei fudge truth, claim first 3GPP NB-IoT demo:

Having forced the different proponents to work together in the NB-IoT working group, the 3GPP’s attempt at uniting the cellular-led LPWAN alternative to the likes of Sigfox and LoRa is beginning to bear (politically-charged) fruit. Huawei and Deutsche Telekom have announced the first installation of the NB-IoT (narrowband IoT) technology on a commercial European network – and they aren’t being completely honest.

Which path will you choose? What way should you recommend to your clients? Will you recommend SigFox, LoRa, Weightless, LTE M, NB-LTE or the new direction signalled by the NB-IoT Working Group?
Currently neither Sigfox, Weightless, NB-LTE, LTE-M or NB-IoT can deliver radio modules plus base stations for a private network. So if you want to cover a city or a larger region with a private network then your path ends at LoRa. If you are interested in a private LPWAN, then I’ll show you the best way and make you an commercial proposal.
