The footwells on the 77W J are much more open than on the CS (and AA772/787) J product plus the seat seems more roomy for me around my shoulders so I’ll give it the edge. Food is a bit better on BA, but for a tatl, sleep is the number one goal, so AA 77W wins there. The air vents on all AA products help a lot, so I’d say AA 77W>AA new 772/787>BA CS> AA old 788/772>old BA J
