the other upside being that - on the 77W at any rate - all seats in the J cabin are much more "equal" than in BA Club World; they are all effectively solo seats...even the centre "pairs" are not really pairs for couples but just inward-facing versions of the "solo" window seats; all seats have direct aisle access; other than avoiding one row which has a misplaced window and possibly avoiding being by the galley/loo for an overnight, all seats are more or less the same...except if you can get into the "mini-cabin" which is always nice
