10-speed Ultegra vs. Dura-Ace

I am considering a component group for a new road bike. Are there any
real advantages for the Dura-Ace group over Ultegra except a little
bit of weight reduction? I am talking brakes and a triple drive train
only, no wheels.

Is Dura-Ace more reliable / durable that the Ultegra group? I know
that Shimano sometimes uses better materials i.e. sealed bearings in
their higher end groups. What do you think?

Well, if you're really concerned with reliability and having a triple,
there's Veloce, Centaur (Veloce with the new Centaur BB!), etc...
