Which is better: breaking the fast in the mosque after prayer, or praying and then going home to break the fast with the family?

If the questioner's intent is about breaking the fast after abstaining from food, then it is recommended to do so promptly, as the Prophet, peace and blessings be upon him, said: "People will continue to be upon good as long as they hasten to break the fast." However, if the intent is about the breakfast meal after prayer, there is nothing specific mentioned in the Sunnah. The Muslim should balance between various interests, such as breakfasting in the mosque with the Muslim community for the gathering of Muslims and the unification of hearts, and breakfasting with the family to bring the family together and strengthen family ties. The head of the family is obligated to balance these interests, keeping in mind that caring for the family and children takes precedence over merely meeting friends in the mosque.
