Either one is good, but if I had to choose, I would choose cupcakes. I would choose cupcakes because you can take it out of the pan easy and just walk outside, peel the paper off, and then you got yourself a delicious cupcake. Also some cupcakes can be decorated from others, depending on the people who will be eating the cupcakes taste. Also you can put the cupcakes in a sort of formation and add candles. Cupcakes definitely broaden up creativity when it comes to parties and events involving cupcakes.
