Y6 is all around better except for reduced flight time. Its the best in wind, you never see props in view on forward flight, great redundancy on any controller, easy to tell orientation in air, fits in car pretty well, only 3 arms to take off for travel or replacement, allows huge props. The hex you will gain an extra minute or 2 and will probably be a little easier to tune. But all in all the Y6 and Bart's XY8 are the best configurations IMHO.
