Two books, two frameworks, where they fight

You've read two competing frameworks and they half-agree, half-contradict, and you can't tell which to trust for your situation. This maps where they line up, where they genuinely fight, which fits your case better, and, the part most comparisons skip, what each one misses entirely. Name the two frameworks and the situation you're applying them to.

Compare [framework A] vs [framework B]. Where they agree, where they fight, which fits [situation] best, and what each misses entirely.
