Size really isn't everything
I would echo this as the biggest consideration:
- light leakage and privacy levels in QF F
I take a lot of high value clients in F/J around the world and even though most prefer to fly QF (as they are AU) and some downright loath Emirates, we tend to end up on Emirates a lot because they offer the option to have a more private F experience with their doors.
QF F I think goes the other way too much - lovely open space but you don't feel like it is 'your' space.
This open space also means if someone is watching a movie it illuminates the whole cabin because the light isn't contained in their own space well enough / the angles aren't quite right to deflect your eye.
Personally I don't really mind - but it's something I've observed with my client base trekking back and forth in F over the last few years.
Hopefully this can be passed on, I would have loved to have gone but I'm afraid I share my F flying around too much
