Because of the cabin layout, in 2A, there is more privacy since the entrance to the seat to the right of you (2F) is from the other aisle. Sort of difficult to explain.
1A and 1E open next to each other, and 2K and 2F open next to each other. Next to 2A and 1K, there is a wall, which gives more privacy.
From 2A, there is technically no one seated right next to you. 2A is my preferred seat in the new F.
