"Best" depends on how you want magic to behave in the story structure, IME.
- Basic spell magic makes magic a matter of scholarship.
- Path/Book magic makes it more a matter of access to ancient lore.
- Ritual Path Magic makes it a matter of illuminated understanding of the world.
- Realm magic makes it an issue of learning the levers that control the universe.
- Magic as Powers is about individual talent and connection with magic.
- Sorcery is essentially a standardised structure for Magic as Powers.
