Personally i prefer bread unless the rice is cooked to perfection
I think rice is slightly better. The reason being is that. It works with so many things. It's literally just a grain. Bread is an amalgamation of certain ingredients. Bread doesn't encompass the amount of palettes and dishes that rice does. Bread does have many varieties though. Like at least a 1000 different types. But rice is something that can always be served with the main dish. And it is really easy to make. much. much. easier than bread at least in the current day and age.
