Not that I disagree but we're comparing the most powerful attack of the tailed beasts to a very basic energy blast. It's like comparing the Kamehameha to a standard Ki-blast. Plus, I would argue that even a fully charged TBB from the Nine Tails is less than double what Aizen did. Again, a basic attack from him was comparable to a TBB from Kurama. If he put some real effort into his attacks, he could easily match the power of the Ten Tails' TBB.
Which is exactly the problem; they can only be perceived and damaged by SPS. Not sure if this falls under Energy Equivalence, given that ordinary chakra doesn't cut it either; a specific ability is required to counter.
Pretty sure it's the Rennagan
