Will I learn more freelancing or working for a company?

Question

I got out of school about a year ago, and have been freelancing since then. Sometimes it seems like it would be a good idea to work for a company for a few years, to learn from people with more experience than I have. But on the other hand, working for myself has let me pursue projects/technologies that I'm interested in learning about, and I'm hesitant to give that up. Any advice?
