Why is Scipio Africanus so highly regarded as a commander, consistently ranking in the top 5 in the ancient world?

Seems like he is only known for winning a single battle against Hannibal. Outside of that I'm sure he was very competent but without defeating Hannibal would he even be remembered? Even without some of Hannibals greatest victories Cannae,Lake Trasimene, etc... he'd still be remembered as one of the greatest generals in history.

Side question: Whose the better general, the guy who hands Rome it's ass repeatedly or the guy who gets to sit back and study that guy who hands Rome it's ass repeatedly for years and then beat him?
