While partnerships sound all well and good on paper and may run low risk, they are still not easy to manage unless your partner is the definition of a perfect partner. While you and your partner may share similar goals and ideologies, the execution you may feel is best could be drastically different than what your partner sees as best and that can cause conflict. On the other hand, if you and your partner have the same view on the best way to execute ideas, then when future difficulties may call suit a different execution and leadership style, it would be tough to adjust. Ideally you would want a partner that has is in a nice middle ground and is able to adjust between leadership styles. Or even better, be that partner.
