Sorry for the extremely long wait. I've been super busy with irl shit. Anyway, here's what I've got for Obito. If it's alright with everyone, I can just apply this and we can finally close this thread.
Tier: At least
High 7-A,
6-C with Giant Shurikens and Stakes,
Varies from
High 7-A to
High 6-C with the Edo Jinchūriki and Bijū
Attack Potency: At least
Large Mountain level (Matched Kyūbi Chakra Mode Naruto's headbutt. Consistently pressured and overpowered Kyūbi Chakra Mode Naruto, who
complimented Obito's strength. Casually destroyed one of Kyūbi Chakra Mode Naruto's clones),
Island level with Giant Shurikens and Stakes (
He was able to cut through Gyūki's tail with the Giant Shurikens, and was able to pierce and pin him down with the Stakes, as well as force Naruto to block the Shurikens with the Kurama Avatar),
Varies from
Large Mountain level to
Large Island level with the Edo Jinchūriki and Bijū (He uses 6 Edo Jinchūriki, who can
fight and harm Kyūbi Chakra Mode Naruto, as Six Paths of Pain. He also has control of the Bijū,
who are individually this strong, and can combine their power by pooling it into a single combined Bijū Bomb)
Striking Strength: At least
Large Mountain Class (
Overpowered Kyūbi Chakra Mode Naruto with his Gunbai),
Varies from
Large Mountain level to
Island Class with the Bijū (Has control of the Edo Jinchūriki and Bijū)

Large Mountain level, likely
Island level (Withstood a headbutt and a
Rasengan from Kyūbi Chakra Mode Naruto. Later on, he also withstood a
Rasengan to the face and a
headbutt from Kurama Mode Naruto, without any major injuries),
Island level with the Uchiha Flame Formation (The barrier was able to withstand a direct blow from
Gyūki. It's also capable of damaging and burning opponents upon direct contact, which was demonstrated when it burned Gyūki's fist)
