Being an ENTJ doesn't mean your strong, there are no more strong ENTJs than strong... say, ISFPs. They are more assertive and aggressive, but that doesn't provide intellectual or physical superiority.
I don't compare myself to types, I compare myself to people. If that person who I'm competing with happens to be an ENTJ, I tend to withdraw and base my arguments on quality > quantity. I smile a lot and act calmly, which makes them lose composure and as they struggle to strike even harder, they lose their grounds. At this point, their defeat is imminent. They're like those boxers who try to win so hard and punch so fast that they step out of the circle and get disqualified. The same strategy doesn't work on other types though.
