Well, as already mentioned, it's become a pretty simple decision for me :
If I can get the route/timing I want, with a J class config of 1-2-1, on a carrier that I know will provide good service + competitive prices (not too difficult the way the biz class market is these days), then I have virtually zero inclination to go 2-3-2.
I will happily continue to fly EK on their 777's in F (where I feel the trip warrants F), and also the 380 in either F or J (although not overly-keen on the 76 capacity cabin when full)
That said, if you can guarantee me Scarlett Johansson as my neighbour on an EK 777 in J, then I'll have no issues at all with their more crowded 2-3-2. Sadly it ain't never gonna happen ...... she'll be tucked away in her F suite ......
Or else on NetJets ........
