What is the word for doing the opposite of advice to prove you're right or can do better doing it your way looking for a more advanced word than defiance or rebel?

The Word you might be looking for is "contrarian." A contrarian is someone who takes a position that opposes the majority or prevailing opinion, often to challenge conventional wisdom or to assert their own beliefs. This behavior can stem from a desire to prove their perspective or capabilities, rather than simply rejecting advice.
