Et al,
I am not partial to, nor am I experienced in any one of the aforementioned aircraft, they are all fantastic machines.
All in hindsight, doesn't that third engine give you a little more confidence when going across the pond? Electrics, pressurization, hydraulics, etc. (possibly) without having to descend to the lower FL's to start an APU and possibly have a speed limit? Dasault does have a niche...
