I flew in new F from STN last Friday.
As known the airport is well below par when it comes to the lounge, no champagne or prosecco for F pax, so we ended going to The Camden pub, which was excellent (ask for Rob the manager to sort you a seat upstairs).
Anyway, boarding was a breeze, and the cabin is out of this world. I have never used the word 'epic' so much. Totally amazing experience. The only drawback is that if you are traveling with a companion the seats are not the most sociable and you're so far apart from the other person you feel that you have to shout to them. For the individual traveller the experience is out of this world. I got the most amazing 5 hours sleep I have ever had on an aeroplane. Being able to control the lighting, and the temperature is incredible, but realistically the temp can only be controlled to a certain extent.
I am just about to fly from Manila back to STN, J then F, with 5 hours in DXB, so that should be another interesting experience.
