The DA crank is only 60 grams lighter. Everything is slightly lighter, total difference between the groups is about 200 grams. You can get half of that by simply using a D.A. cassette (I think that's 70 grams or so) and BB, which you can always upgrade to for relatively modest cost. On my Scott Addict I have Ultegra, but the BB and the Cassette are Dura Ace, so the net weight savings for me upgrading to D.A. components would only be about 100 grams at this point. I can add Zero G brakes and save that, but I'm very pleased with the Ultegra braking.
So the short answer is that yes there is a functional difference: Ultegra 6700 is
better. Go figure.
