He is able to continuously put Jinjuurikis in Genjutsu though. It's not like Tsukuyomi that affects their perception of time so the TB can't get them out in time. It's the Jinjuuriki in Genjutsu for extended periods with no breaking out despite them having a Tailed Beast. Itachi and Shisui are renown for Genjutsu, but Obito has that ridiculous feat in the area too.

I don't think any of their Genjutsu besides Tsukuyomi could affect him, (since Koto is restricted).
