You can't compare the two, one is a library / framework to build a site content and render it, the other is a full program to deliver content that has already had its format determined by the developers.
You are trying to do the equivalent of performing a comparison or drag race if you like between a drag racer and a kid in a go-kart.
If you wan flexibility, then go write code.
If you want to be limited, Use a library.
If you want to be stuck with what you're given, then go CMS.
