Okay, I change my answer. I'm going Minato on this one. I briefly forgot that Izanami does not work that way (sorry, I tend to forget sometimes) and I'm not sure if Itachi's low chakra reserves are related to his illness or not, but either way I think Minato would have a good shot. Itachi relies too much on genjutsu to be honest and, as I've been corrected, I don't think there's any genjutsu that can catch up to Minato. His quick reflexes enable him to easily dodge Amaterasu and take down Itachi.

Honestly, FTG is the bane of a Sharingan user. It explains how Tobirama, a FTG user, was able to defeat Izuna, a Mangekyou user, who was said to be on par with MS Madara.
