The three major sociological theories are usually identified as structural-functionalism, symbolic interactionism, and conflict theory. of these, which do you find most interesting and/or useful?

In my opinion conflict theory is one of the most interesting sociological theories, these are considered as perspectives in disciplines such as sociology and psychology which concentrates on a materialist interpretation of the past, argumentative analysis, a critical stand toward already residing social arrangements, the political vision of revolution. These theories tend to draw awareness to power differentials, example class conflict.
