I would choose partnership over sole proprietorship. The reason being is that your not alone. You will work others to make your business prosper. In a partnership there is not going to be one idea but multiple ideas that will be heard and can help the business. The financial portion of partnership will be less than sole proprietorship because there will be others that will assist in finance. There could be bumps along the way but it is normal in any relationship and having a relationship is good because you will be able to count on other to help.
