Just took a flight on the 777 last weekend. 7A hands down is the best seat in the BE cabin.

It has additional privacy & storage but as well much better cabin service.

Few notes:
6A was the last seat in BE forward cabin to be served. Due to seats 7A & 6B being serviced primarily by the 2nd cabin FA staff as well as forward cabin staff, the service is excellent. My wine glass was refilled twice before 6A was even asked for their drink order. The meals in seat 7A were served nearly 10 minutes before 6A. The only downfall is the view. You must be reclined to really glance out. When you weigh the service though, I think it definitely wins!!
