This is particularly true with the new Polaris seat. If you want all aisle access without any overlap of one persons body to another, you'll have to fly F on a foreign carrier (but not BA).
Or anyone with the Apex J seat which is my favorite J seat. Unfortunately it's hard to come by in the US apart from JL and KE.
You still have some overlap but it's managed in a way that prevents the head next to feet thing (especially if in the middle "2" of a 787) and even on the 777 with 2-3-2 the footwell is much more open (closer to the TK 777 style) so you don't bang against the footwells and the person in front of you like you do on these other seats.
