Of the current Q-suite equipped flights, what's the pros/cons with the current aircraft type?

I think I saw somewhere that the the A350 pros are that they're quiet, but cons are lack of air nozzles? (as compared to the 777?)
But there's other aircraft types, and not sure if there's other pros/cons

Personally I'm not terribly concerned about the noise,unless it's like the Delta MD-80 (man those things are atrocious).
But I also don't like sweltering on the plane either.

Thanks!
