Personal choice really, I really liked the hood and the shifting of the SRAM, the two click system seemed to be pretty intuitive, what I am saying is that you should give everything a try before settling down to Dura-Ace (although the Di2 is to die for).
We got some bike in our shop that have full DA groupset (Pinarello Dogma 60.1) and one with a full SRAM Red groupset (BMC Team Machine SLR01, the one with the quill seatpost).
