It is clear that LoRa is de facto dominant in a few (mainly European for now) markets in the public IoT network space. LoRaWAN has the benefit of being an alliance with an Open approach instead of a proprietary one. There are also technological differences between the various solutions.
However, the main question is and remains: What goals do you want to achieve with your IoT project?
No technology is perfect. The openness of LoRa is a benefit compared with the proprietary approach of Sigfox but, along with its reliance on unlicense spectrum this openness is also a problem.
There is never a one-size-fits-all solution. It is rarely about 'this' versus 'that' technology. In most cases it is about 'which mix of technologies will make me reach my IoT projects goals?'.
