classic juggernaut vs. true adamantium I would as they are equal.
is mojo world magical? also since when has shatterstar sword shown any magical properties? just because it was made in a realm of magic doesn't mean it's effects are magical.
The only things that effected true adamatium are extream magical power (like king thor level) Jugges has never felt anything like a king thor blast.
Juggs doesn't effect things on a magical level it's physical force you know like when captain marvel hits superman it doesn't cause a magical attack but a physical one. how ever this is not important since the thread writter wants to know what more durrible and I think there equal.
