We can make a really general assumption, let's say every enemy deals 66% of it's main damage type, and you don't die to the damage you take. That means a fully stacked adaptation gives 60% damage reduction against that one enemy if you can't stack the other types. (They deal 40% damage to you instead of 100% AFTER armor)

Now health conversion: when does 1350 armor reduce current enemy damage by 40%? It happens on exactly 600 armor. (changes 33.3% damage taken to 13.3% damage taken with fully stacked HC) If you have more armor than that, the reduction won't be this effective.

So, on 600 armor, a fully stacked Adaptation and a fully stacked HC reduces enemy damage the same. (In reality adaptation reduces more, and for a longer duration, but let's ignore that) Under that HC reduces it more, over that Adaptation, and there is a thing called Arcane Guardian, that gives exactly 600 armor on getting hit (with a good proc chance), so go figure, that's why I didn't want to factor in Adaptation's other pros.

The saving grace of HC, if you can stack it without getting hit (anyone can do it with the sentinel mod, or Nekros with despoil) In 9 hits with adaptation, you take 8.94 hits' damage. Yeah, Adaptation reduced the damage's 0.7%, basically nothing. So if you cannot survive the initial hits (and there is no-one to revive you), Adaptation won't save you, it is the same as getting hit with 0 stacks in HC, I didn't even have to factor in warframe shields, so yaaay for me.

In reality there aren't many enemies that just oneshot you (or 9, for that matter), and the fodder can easily stack your Adaptation up, even to damage types you wouldn't get on heavy enemies. So in my opinion use Adaptation on already tanky, or semi-tanky frames, and use Quick Thinking on squishy ones -oof-. I really like the consistency of HC on a few select frames though (Nekros, Nezha), but you can get the consistency on Adaptation as well if you pay attention to what is happening around you, which won't be a thing when you get into a really long farming mission with Nekros.
