I'm absolutely sure its Shisui for these reasons:

1. Shisui may have survived the fall off the waterfall because technically we didn't actually see him die. Also if he's powerful enough to unlock his Mangekyo Sharingan he might be powerful enough to survive a fall. 2. He has a strong connection with Itachi, saying that Sasuke is a disgrace means that the person has a strong relationship with him or praises him for how powerful he is. 3. The boy used the leaf body flicker jutsu. See as that was the first jutsu we saw from the boy might have gave us a clue that the cloak man was Shisui since he is a master of the technique. Not only that but the body flicker jutsu had leafs in it, Konoha shinobi add leafs to their body flicker most often.
