ELI5: Are swords and katanas made of meteorites or other space rocks are better weapons than their Earth-counterparts?

Just saw a photo of that katana made of space rock and I'm curious to know if it's a better weapon than those made of metal. Also, what is the ideal Earth element that is best suited for swords? Thank you.

In the modern day, we can exactly replicate meteoric iron. So there's really no advantage.

In primitive civilizations, it's nearly impossible to find metallic iron except from meteoric iron. Because smelting iron ore is relatively difficult, this means that almost all ancient iron implements needed to be made from meteoric iron.
