really dissagree with this - 11A/K on the 77W is quieter and roomier than any other J seat in the system in my opinion. Plus, the oppurtunity to use bookable upgrades, upgrade awards, and rarely (but nonzero) chance of an op up. Even the bulkheads on the 359/K have much smaller footwells plus much more light / noise with the lavatories being right in the cabin instead of in the door/galley areas. The A350 is a wonderful aircraft - CX's chosen layout, however, in terms of lavs and galleys, is a big step backwards.

However, at the end of the day, I wouldn't go out of my way to book either - go with whatever works best with your schedule.
