I agree with you AT, the A350, isn't in my view, one of the best looking of aircraft, and only looks aesthetically pleasing from certain angles. The B787-9 is much better looking! The A380 is aptly described as a whale. Looks are one thing, but it's performance and economics that count!
Modern aerodynamics seems to be moving away from sleekness in many aspects, the newer High Speed Trains from France (AGV), Japan, China, and Spain are not as good looking as the previous generation, some of the Japanese/Spanish ones being fairly ugly.
