I won't even try to say that diablo didn't have some major kinks for the new mustang when it came out - but they have squared away just about all of them. The mulitple tune capability was the biggest difference until diablo corrected it. I agree it is mostly on the tuner and comes down to which one he has more experience/knowledge with. And I would tell anyone with an auto to get the sct for obvious shift reasons.
