Its a...wait for it.....a BOEING!!!
Boeing engineers designed the 777 to fly like an airplane. There is nothing magical about this aircraft. The fly-by-wire system works well, although the autopilot works better.
As for manual crosswind landings, when I teach this aircraft and those who look at the training manual, will see that a 'crab-decrab' is the best maneuver in this airplane. There is actually a note in the training manual that talk about some complications of using the sideslip method, during gusty wind conditions.
In short...this airplane is a dream to fly.
