Many times people confuse knowledge with wisdom, but those are two different things. Knowledge is usually acquired through learning at school or work. When you go to school and learn math, English, social studies, or science, you are getting knowledge about those subjects and the skills that go along with them. Wisdom, on the other hand, is usually something that you are born with.
Only certain people have strong wisdom in them. If you know, you can generally answer academic questions, but if you have wisdom, then you can usually advise people about something or help people figure things out. It depends on what you are trying to achieve to determine if having wisdom or knowledge is better.
