Based on the following:
- happy = aisle with one person inboard of aisle, or window one seat away from aisle
- neutral: aisle with two people inboard of aisle, or window two seats away from aisle
- unhappy: middle seat one seat away from aisle
- very unhappy: middle seat two seats away from aisle
The possibilities are:
- 2-5-2: 6 happy, 2 unhappy, 1 very unhappy
- 3-3-3: 2 happy, 4 neutral, 3 unhappy
- 2-4-3: 4 happy, 2 neutral, 3 unhappy
</font>
The 2-5-2 layout is 4 happy, 2 neutral, 2 unhappy, and 1 very unhappy. The inside aisle seat has two people next door (although the middle-middle person is "shared" by the two inside aisle people).
This makes it about the same as 3-3-3. One nice thing about 3-3-3 is that the dreaded super-middle seat of 2-5-2 does not exist.
According to my calculations, the center of gravity for a 2-3 layout on a DC-9 is 1/4 of an inch away from the center of the fuselage. The center of gravity for a 2-4-3 layout on a 777 is 1.8 inches away from the center of the fuselage. That shouldn't make a difference.
