JLPT Grammar Comparison

ものを vs のに

How to tell them apart

ものを carries the speaker's strong discontent or regret over how things turned out, often implying a missed better alternative (すぐ医者に診てもらったら治っていたものを). のに simply states that the second clause runs contrary to expectation, with no necessary sense of regret (高いのに美味しくない). Swapping them loses the emotional weight that makes ものを natural.
