Finnpog,
No, it's simpler than that. The Rafale looks like an aircraft should, not like a bunch of bits from multiple manufacturers just bolted together.
The French know how aircraft should look; sexy, curved, aggressive, useful. The Typhoon looks like a bunch of sharp pointy bits glued together.
Looks sell.
The UK used to know how fighty planes should look. They lost the plot though and decided computers know better. You then end up with things like the AEW3 & the Typhoon.
