I have run, Azimut, Ferretti, Sunseeker and Princess yachts in the past ranging from 47-90ft and if I could say one was better than the other I would..... but I can't. They are all good at what they are meant for and built in the way to suit the design brief. My favourites were the Sunseeker as the engineering was somewhat better that the others, and the Princess for it's slightly more timeless design, but thats my opinion.
Another yacht I ran was a Dominator 65 which I covered near 2000 miles in the year on-board. Although there were some design flaws, she was a nice yacht, that had performance that matched her looks.
