I've been reading answers to this question but none of them answer it. Who is stronger in magic and swordfight? Who would win? People say Gandalf is equal to Sauron, but I find that extremely hard to believe.
While the Witch-king is said to be the strongest and most fierce of Sauron's servants, he was defeated by Aragorn. The Witch-king cannot be killed by man, but Gandalf isn't a man. If the Witch-king is so strong Tolkien and Peter Jackson did a very lousy job at showing his power. They make him seem like a normal man, yet he's the most powerful servant of Sauron. If the Witch-king can be defeated by Gandalf or almost anyone with magic powers (which it seems) then why even create such a "a powerful being yet defeated almost by anyone"? Logic dictates that "the evil servant will always defeat the hero".
