Performance wise there would be no difference from what I know.

Why are you asking? Are you thinking of buying a Mach, have a choice between an auto and a manual? If that's the case and you want to end up with an automatic, I'd certainly get the automatic to begin with and start the mods from there.
You pretty much nailed it on the head.
My only worry from this point on with an Automatic is researching to see if I need to get different mod parts than a manual. Not very car educated I'm afraid.
