I have my first trip on a CX A340-600 coming up, in Business. Is service/ambiance in the rear Business class cabin noticeably better than up front? I prefer a window seat and it seems there aren't that many good ones -- either too close to galley/lavs or missing a window. It even seems row 20, the only window seat without a warning on seatguru or seatexpert, is over the wing and might have an obstructed view as well.

Any personal experiences / suggestions?
