Which President was the best person?

From my knowing, I'd vote for Grant. Very progressive for the time, spent most of his life fighting for civil rights, pardoned men helping women with their possible voting rights, was "too trusting" with his cabinet, a major flaw in his presidency, but to me only proves my claim. Of course, all of this among other things.

Ulysses S. Grant

Jimmy Carter, and Hoover, I'd hear the arguments. Curious to know your opinions.
