Personally if you can't get the Room or Suite I'd give the a350 a try, but I haven't yet had a chance to fly an a350 so comparing its humidity and cabin altitude to the 787 is a big part of my interest regardless of carrier. Interesting comment on language barrier - I have always found ANA FAs to have decent English although I generally attempt to converse in Japanese. We sure do get spoiled in expecting even FA-level foreign carrier staff to speak our language!
