Amphetamines are certainly more dangerous. They actually make you feel good/euphoric. Modafinil just makes you feel awake.

I've heard people complain that amphetamines increase focus at the expense of creativity.

Another related danger of amphetamines: because they make you feel good, they create a dopaminergic illusion of proficiency. Whether or not they are actually improving your proficiency can be difficult to judge.
