I like the small cabin when in Y, most of the bathroom traffic goes towards the back of the plane and you are left alone. Row 12, AC/HJ is where to sit, 12D has the arm that goes up and the rest are hard for the tray. Row 14 sucks as the storage and wall prevents you from reclining. You do get some traffic from the back from those who are curious of what the cabin looks like.
