I personally prefer 3A or 3F (it depends on the direction of the flight, eg SFO-HKG by sitting in 3F, I can see downtown San Francisco when taking off). 1B the only seat in row 1 for skysuite configuration is too closed to the wall in my opinion. Row 4 is too close to the galley and the lights from the galley can be disturbing. Hope this will help.
