I've used all manner of groupsets from Shimano, Campag and Sram.
My Madone has Ultegra 6600 I find it shifts better than the later Ultegra and DA with it's bar mounted gear cabling.
My Donohue winter trainer has Campag 10sp Centaur
And my latest purchase has Campag Record 9sp and the shifting is the best out of all of them, more precise shifting and I have more confidence shifting under load.
