Best kind of icing for a red velvet cake?

Ewww. I just don’t see the point in seeing if you like a type of cake (devil’s food, red velvet, what have you) by making it from a box and buying the frosting. That’s like seeing if you like mashed potatoes (which can be delicious with milk and butter and everything all smashy) by using freeze dried potato flakes, powdered milk and butter buds.
