IMHO, 3F for an experienced traveller is one of the 8 best Business class seats on the aircraft. I'd rate it 5th or 6th. (14A/K > 5B/J > 3D/F > 14B/J > remainder).

None of these 8 seats require a traveller to climb over or be climbed over when aisle access is desired.

3E/F have substantial personal storage lockers - big enough for a rollaboard and the personal item.
