Wife and I were 13EF ATL-SAN yesterday. Great seats! Infinite legroom plus underseat storage make them desirable. They do have fixed armrests w/tray table/IFE, though, and the overhead bin directly above houses some emergency equipment. Recline was good, and the FA jump seat is no big deal. Also, we were right by the engines, but they were quiet at altitude. They are among the best non-F seats on that bird in my opinion. WAY better than 19F on a 752 or anything on a 739...
