Man its been a few years (and a few more pounds) since I was road racing but I preferred Dura Ace over Record mainly because it was a clean functional design that equaled or exceeded the performance of Campy for way less money. Remember amateur racers spend too much time training to be actually holding down jobs that pay money!
I never developed an attraction to the Campy look, especially those crank arms, and went strictly for function. My first Dura Ace groupo was a 7 speed hub (13-21) on a 56cm Land Shark frame. Very stiff...too stiff for training, beat me to death, but very responsive in a crit. I raced Cat 3 for 2 years with that setup - heck was beating on the door of Cat 2 but then my future wife entered the picture
I always wished I could justify the $$$$ for a TI frame but life played out differently...I got my 911 though! I still ride from time to time on my old Trek 2300. The rear triangle and forks are aluminum and the rest is carbon - stiff enough for climbing and sprinting but still compliant to absorb the long day bumps. Nothing fancy for sure...very retro in today's pack, but for my needs serves me well.
To answer your question - money no object I would go TI otherwise the money saved could be applied to some killer wheel combinations.
