Jefferson was way too self-righteous -- far too convinced that he was on the right side and everything he did was justified. Hamilton seems a little more level-headed.
But then, Jefferson won -- at least in his own era. If Hamilton had lived and come back into power, he might well have become as big-headed and overbearing as Jefferson was.
I have always found Alexander Hamilton more interesting than Jefferson. He had to struggle more, and was constantly trying to prove himself, whether it was trying to enter the echelons of society that he aspired to, or storming the British fortifications at Yorktown, he had more fire.
Jefferson seemed laid back (relatively speaking) in comparison.
It seems to me that Hamilton thought more about the nuts and bolts of a republic (certainly from his contributions to the Federalist papers) and Jefferson was more of a big picture guy.
That said, I admire Hamilton more, because he was by all accounts more loyal to Washington than Jefferson was.
But I do admire much about Jefferson as well.
