It depends on a number of things. For example, what do you expect to get out of it? Journalism is much more likely to lead to a reliable income than creative writing. Creative writing, as I understand it, tends to be fiction for publication, while journalism is writing articles for a newspaper or magazine.
If money is not an issue, you ask what you are good at. What are the requirements of the different types of writing, and what best fits your talents? Logistics such as available programs at your school must also be considered.
In journalism, you probably have more structure from your supervising editor. In creative writing, the ideas and incentive to write must come out of your own head and heart.
Not knowing you or your situation, these pros and cons are the best answer I can provide.
