They both serve different purposes.

Kimono itachi is meant to counter teams based on chakra, especially ones that have innate generation and cant dump it effectively (think edo roshi teams, kakuzu teams with taisho konan- this might backfire hard if you buff kakuzu so he actually 1shots itachi with full chakra!, madara founder teams). In current state of the game you are likely to deny attacks r1 from all earth main teams. In addition he has a nin buff for the column he's in. He dodges mysteries, so his dodge isnt benefit the whole team. He's strong and annoying, but niche pick nonetheless. As for price, about 200cp+ for frag, I think only lucky stars had his frags so far.

Edo itachi on the other hand specializes in taking out of commission 1 of opponent units for 2 rounds. Can dodge chases, so his dodge benefits whole team, as it has a potential to deny high combo chase from stronger units. In addition he shines vs pure nin ninjas (kakuzu standards, sosp standards, all agk teams) effectively halving their dmg for a brief while. And then there's a mirror, so you dont accidentaly cc yourself. He's overall good and can fit into pretty much any team. Top tier support as of now.

Also playing vs kimono itachi without having him is ok. While playing vs edo itachi if you dont have him (and any mirror at all) is annoying as hell. Kimono might be better in certain scenarios, while edo is more flexible overall.

Well it's hard to choose. Kimono Itachi increase mystery cooldown by 2 round and cancel standard for the teams that have more than 50 chakra. he can pretty much shut down a whole lineup. While Edo Itachi needs control to cc enemy's position 1 and I'm not sure he can even with the treasured gourd.

If you are a 700k+ whale with a 200k+ move 2 you can do it

That said: both the itachi have flaws but imho currently edo itachi is better simply because full taijutsu teams or do not exist or get easy controlled by him.

Alright thanks for your answers all.

FLAWS?? edo itachi strong standard best cc mirror doge chase. you expectation is too * high.

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.

Yeah but I'm not sure I can cc a position 1 when I will get to 300k power so his mystery will only be able to get rid of shield and debuff. While kimono Itachi doesn't need control to increase mystery cooldown.

they both work great

Edo itachi personal endurance is close to unexistant.

1 hit from a decently stacked edo hiruzen or edo han standard attack or any strong move 1 nin/tai mysteries (like naruto hokage minato's or kushina habanero) pretty much oneshots him.

He is op just because most of the current op mysteries/chases/standard attacks are full nin.

go for itachi kimono, even with itachi edo on your team, kakuzu will most likely kill your backline with 2 standards anyways. On arena same thing, he reduces the damage in half but kakuzu still deals 3k crits on your team. Better to stop him from attacking then to just reduce his damage, cause reducing his damage won't help you at all

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.
