I would go back to Campy in a second if it weren't for the fact that I usually get my groupos as hand me downs from a racer friend, so I just get what I get.
Another thing to think about is weight, I am under the impression that the full Di2 set up is heavier than a Campy Chorus set-up, but I don't remember where I got that information from. You may want to ask. Or you may not be concerned with weight to the same degree as some riders.
Good luck.
