Lots of people like 9A on an non ps 752, but others avoid it -- probably a matter of whether they can adapt to the protrusion (about 6-8 inches IIRC). People congregating near the toilet tend to trip over you much let frequently than in 9B/C. Just a few other things: OHB space in row and 9 and 10 can get tight because 8D/E have no OHB space. If squeezed for space, however, the FA's will often allow you to put you stuff in F, underneath the seats on row 6, or in the OHB there. If you board early, you will have a steady file of people passing right in front of you until boarding is complete -- so if you like peoplewatching, it is good. But if you want to get some work done, it may be hard as you will be distracted. Also seatguru.com says that air can get past the door seals and make for a cold flight -- this is usually true so you might consider grabbing a blanket, if one isn't already in your seat.
