Wealth is not a synonym of money. For example, health is a wealth. And there are a lot of people who are ready to sacrifice their entire tangible wealth to be healthy, but unfortunately, it can't be helped in many cases! there isn't an exclusive relation between knowledge and wealth, wealth an be brought by knowledge , and knowledge an be brought by money sometimes ( like enrolling in a good university or college, get the access of the most helpful educational material ....etc.) Both of wealth and knowledge are tools, and only their use can determine how useful they are. It's up to us to choose the appropriate tool to achieve our plans.

hi dear , i think there is no relation between knowledge and wealth, poor and rich have access 2 it ,

You should as "Which is better". Knowledge brings wealth. Wealth doesn't bring knowledge. So I choose knowledge.
