787 is an impressive aircraft, however so is the A350. Given a choice between flying an Airbus and a Boeing aircraft, based on those I've been on widebody wise (747, 757, 767, 777 and A330, A340, A380) I'll take an Airbus any day, although all the Boeing aircraft are great as well. I have upcoming flights booked on the 787 as well as the 747-800 in the next few months, so I'll be able to see firsthand how great the new Boeing lineup is. Hopefully in 2 years time I'll also have the A350 experience.
And I stand corrected on my comment about climb angle, I completely forgot about standard combat take-off procedures, which is sad considering I control combat aircraft at work. However, like little old man said, there comes a point where the aircraft will fall out of the sky if they maintain that angle as lift is no longer generated.
