Well, it's not the best example for frog kata on Obito. As Obito's Kamui lets attacks phase through him. Since we have the feat of Naruto's frog kata knocking out the preta path, we can make certain assumptions about the durability of the path and frog kata's strength.

It's difficult to compare the power of frog kata from one instance, to something like Tsunade's strength or the 4th Raikage's strikes. From observation though, it's clear that frog kata has less destructive power than Tsunade and Ay. There could also be a durability factor in that, the preta path may not have been particularly durable and thus vulnerable to physical attacks. So quite a few unknowns.

Back to Obito, we know that the deva path was defeated by a rasengan. And we know that both 14yr old and adult Obito tanked a rasengan and was not knocked out of commission. It's not too much to say that Obito has significant durability to tank frog kata and in addition having Hashirama's cells to heal damage.

Using frog kata against someone like Kakashi, not sure. Kakashi seems to have average durability and was able to tank shinra tensei strikes and still continue fighting.
