I dont know if I would say either are nessarily pushy and loud (then again everyone is compaired to INFJs ) but I could say they are activity oriented. ESTPs can be business oriented but unlike ESTJs seem to like more fast paced risky ventures, salesmanship and twisting figures and minds with fast talk and get rich quick schemes. Their emphasis is more on immediate success and the popularity and freedom it brings. ESTJs are perserveering and hard working, less flexible and more conservative. They logically build block on top of block and try to plan for the future and security. ESTPs are more "live fast and die young" and he ESTJ is more " a penny saved is a penny earned". These of course are stereotypes so dont go crazy.
