TBN is more powerful overall, but in big pulls I feel like it gets diminished considerably. It's good when paired with certain CDs, but otherwise it gets eaten in seconds. Sheltron is active the entire 6 seconds no matter what, and like I said before, the more damage coming in the more powerful mitigation is. TBNs shield, however, doesn't scale with the amount of damage you're taking.
Also, AD is better with big pulls. You implied Paladin has the worst defense overall, though, so I kind of shifted perspective to overall. AD is only really a good defensive ability on substantial pulls.
I feel like when being played optimally all of the tanks are pretty well balanced between defensive and offensive capability. Paladins just have an incredibly powerful utility that allows them to sacrifice damage in order to become by far the most resilient tank in the game.
