Best way to integrate Velux roof windows

What is the best way to integrate Velux motorised roof windows? From googling around there seem to be at least three possible options as follows. Which is best? Resp. Cheapest?

  1. via the Velux KLF200 hub which has an openHAB add-in
  2. via the Velux Active hub, which I think provides some kind of NetAtmo integration
  3. via the Somfy TaHoma hub, which supports Velux, and has its own openHAB add-in
