Percy is still exceptionally strong though, being able to break the horn of a Minotaur, but before others start referring to his feat of holding up the sky - that was more due to the fact that Percy (in Poseidon's words) has "great courage and a true heart."

But yeah, Magnus still is the slightly stronger one.
