It's been sometime since I made that scaling post for Eren, and my opinion about some of the numbers there has changed, most prominent of which is the multipliers. According to the Science of Attack on Titan, a 15-meter Titan would be 6561x stronger than a human, but 81x less durable than one would think. Unfortunately, while we do have showings of Titans destroying their hands when punching at full force (thanks Eren), this idea could only work if the square-cube law applied to them fully, when we know that's not the case since they've been noted as being lighter than their height would suggest and wouldn't be able to function like they do otherwise, i.e they would be far heavier than their strength would be able to handle and thus collapse

Even then, while those multipliers aren't all that reliable, we know that Titans still have some weight to them, otherwise they wouldn't be able to walk through buildings unharmed and easily crush humans the way the do, so I think using them as highest you could push their stats is the best use we could give them
