Well one cannot say for sure that Hillary Clinton would have been a better president than Donald Trump for a number of reasons. Firstly, she has not been in presidency before so one cannot say what she would be like with great certainty. However, one thing is for sure.
Hillary Clinton would have been far more respectful and open to the minorities of the country. She would not encourage any racial differences that based on her own biases and would hence promote the formation of a more tolerant nation. This is something that America is badly in need of as of yet.
