As for Dura Ace, I have experience with Dura Ace 130BCD rings, only.
However, regarding Sugino, I recently purchased a Sugino 75 Track ring, the one that looks more like a conventional road ring than the Zen or Messenger rings.
The Sugino 75 Track ring exceeds any design and engineering expectations I could have possibly entertained.
Sugino addressed details that I didn't know existed until I mated the ring to my Sugino 75 crank and started closely examining them both.
The Sugino 75 Track ring retails for $125 and I got it for $97.
It looks and behaves as if it costs twice as much.
The Dura Ace 144bcd offering might match or exceed the Sugino 75, but I have no experience with the Dura Ace 144bcd rings.
