Hmm... "your level of mastery of it will ultimately decide how strong you are" though is true but ain't a complete statement there.

We have seen how someone use haki to win against a DF (Pekoms one-punched Caribou), and then we have also seen how someone use DF to win against haki (Law epic-slashing Vergo). I guess you can agree Vergo has quite a good level of haki mastery, yes? But it does not mean he is "very" difficult to fight against. By now, I think you are starting to get what I am implying...
