I'd say cruise Mach is much more important. For cruise performance I would vote for the B777 wing as being the best of the heap. I has nearly the speed of a B747 with far less wing sweep. That's airfoil technology at work. Mark Drela First Law of Aviation: MIT Aero & Astro "Takeoff is optional, landing is compulsory"
