Alexander the Great inherited most of his success from his father. Although a competent and ambitious commander, he would have been a nobody if his daddy hadn’t been Mr. big shot.

Philip inherited too. He built on his father's very considerable success, just like Alexander built on his father's.
Amyntas III -> Philip II -> Alexander III
They're a dynastic set. There's not a lot of sense in separating and comparing them.
But in terms of lasting impact, it's not even close. Philip II exerted control over Greece for a brief time but didn't change much. Alexander changed the entire world permanently.
There are plenty of cases of people who rose through the ranks to become powerful beyond anyone’s wildest dreams.
Adolf Hitler, maybe the most famous example.
