I guess it could be that it's easier to build. You have a tower that only gives structural support and you have a gondola that only deals with all the rotation. In general it is difficult to have something that rotates and also carries a large load. And the rotating gondola technology is a solved problem. Plus you have a large rotor area that is always facing the wind instead of half your blade area going opposite to the wind. These are just guesses though.
the rotors of most windmills are on a rigging that allowed them to rotate to face the direction of the predominant wind at any given moment, thus the phrase “always facing the wind.” it’s not anything mind blowing or incredible.
