Power wise we can put Itachi somewhere in the Sannin regime. Where, i don't know since we have no definitive proof of the limit of his powers. Edo Tensei are always questionable sources (indicative but not definitive), since their regeneration (chakra and physical) kind of removes the most important weaknesses a Ninja has.

Still, Itachi's limits were roughly using each MS power twice. A healthier Itachi isn't likely to spam it 10x as much. Sasuke's MS use was downright reckless and he didn't use it more than two or three times. In Sasuke's case there were also significant drawbacks from MS overexertion (losing focus for some time), so the limit for his MS powers seem set.
