On the 744s 14AK and 62/64AK are outstanding -- you don't need F if you have those seats.
In terms of Club Kitchen, my flights to and from EWR/JFK - I don't think there is anything other than chips and chocolates anymore Eastbound, and Westbound I thought it was about the same. I was told westbound Club Kitchen only has sandwiches to NYC at certain times of day. I think the hot food was removed along time ago.
Compared to QR 777s - they J seems much wider - and if you don't have somebody next to you, it's nice.
QR's food service - quality and quantity - as well as snacks are far ahead of BA from my experience - but perhaps they have a different offering on US-DOH flights than shorter flights to the UK.
Overall, the CW seats for many years with far ahead of anything else -- it is only recently that other airlines have caught up and in cases passed the CW seating by. CW is not state of the art - it's also not bad. That said, BA could do a better job cleaning its cabins.
