My complaint with the new F is that the dining table does not slide forward far enough to get in/out of the seat easily.
I have a 32" waist, and found it pretty tight to slide past with the table up.
The legacy F without the big video screen provides much more room to maneuver.
Just a little ding in my book.
I've got 3 longhauls on LX next week, and am looking forward to the old F cabin.
