I prefer 6D over 6E for the following reasons:
- 6E (also 4E on the 788) look into the galley and there is a bright ceiling light above door 2R can be on often during the redeye flight. it bothers you when you watch the inflight entertainment or working on the computer or reading.
- 6D (also 4E on the 788) is closer to the larger lavatory next to 2L
- 6D provides quicker exit out the plane
- If in 6E, the person in 6D can look at what you are doing on the computer or see what you are doing because the angle of the seat.
