Edo itachi would probably be better since as stated he's more fleixable. Not only can you shut kakuzu teams/AGK/Hiruzen/Ronin teams down if they don't have mirror you also reduce nin dmg by half so even if it gets reflected you'll still have his passive reduction. Kimino Itachi is something I'm going for along with Summer Ino but again that's with a kakuzu team in mind anyways. Kimino Itachi is still more niche and not as verstile as edo is.

It really just depends as somee have said. Edo more versatility kimino more hard cc in the form of sleep an the mystry. Plus Kimino can't be target by the first 2 mystry's so there is also that, while Edo itachi from personal experience can sometimes just let chases hit him tthen decide at the last hit not to so it's kind of random how good it is.
