more fearless
more leadership
more authority

more everything!!!
There now you know the difference.
AND DID I SAY MORE POWERFUL!?
Only faster - (Not really, ENTPs are way more opportunistic. Thus I would argue that they are faster. I am interpeting faster in a more specific way to ease my point down your throat.)
more ambition - (Yes definitely.)
more powerful - (Power hungry. When it comes to people I would say ENTPs are more influential thanks to Fe Ne. But then again ENTJs are officially powerful, from my experience.)
more successful - (In what? scaring people off?

)
more dominant - (YESSSSSSSSSSS, but that's not a good thing. People laugh behind your backs you know? if you are dominant.)
more machieveillian - (ENTJs are
NOT machieveillianess. ENTJs are planners who plan things and see things unfold. machieveillian would LET THINGS UNFOLD and slightly push thing around to get what they want. That's ENTP. And that's machieveillian.)
more intelligent - (Ohhhhhhhhhhhhhhh.)
more extroverted - (Noooooooooooooooooo. Barking at people is not extroverted.)
more fearless - (When there is crisis ExxPs always seem to have the best guns. And fearless applies to situations that you do not know what outcome it would result in. Such as a crisis. So who saves the day or who would survive such a situation? Meaning who is more fearless?)
more leadership - (Ne - seeing opportunities everything, combined with Ti and Fe (hugs kisses and motivation with a lot of manipulation.)
more authority – (Yes.)
more 8w7 – (Yes.)
more everything!!! – (No.)
