I'm an endurance cyclist but I have a longer torso and shorter legs (in relating to average), so the Emonda is a much better fit for me. Conversely, the Domaine felt all wrong -- but that's just me. And I'm an endurance cyclist.
You have to find out yourself which type of geometry works best. If you can't find a local fitter, than ask if the dealer offers arrangements for extended, back to back test rides. Then you'll have a good idea.
I hate the terminology that the indutry is using to catagorize bike like the Domane, Defy, etc. Almost any bike that let's the rider produce power comfortably, will work as an endurance bike. Proper bike fit,and clearance for wider tires will make almost any bike work for endurance riding.
I have a body type that's the opposite of your's, so a Domane is a perfect fit(with about 5" of drop to the handlebars).. It's far from what most would call an "endurance" fit, but it allows me to produce power comfortably, and gives a nice aero position in the drops.
