Vibranium is beter
in one comic book Wolverine tried to cut though Cap's shield and it didnt work, another time Hulk punched Black Panther, and it absorbed the shock from the punch and didnt do anything to him, he didnt even flinch. secondly is were talking about Cap's shield vs. Wolverine's claw, Cap's shield still takes it, contrary to belief vibranium can be broken, Cap's shield has been broken before, but he took it to an Asgardian blacksmith, who not only was able to recreated it, he infused it with Asgardian magic, like Thor's hammer has, making it indestructible, and therefore making his shield one of the most powerful things in the universe
in conclusion:
any and all forms of Vibranium is better then Adamantium
If I was making a weapon I'd use adamantium.
If I was making an armor or shield I'd use vibranium (for it's impact dampening properties).
Adamantium has a greater tensile strength. Vibranium has better sound/energy/impact dampening properties, and iirc, it's properties also allow T'Challa to run up walls.

It'd have to be a small weapon (like a bullet for a specially made non metallic gun). The more anti-metal you have the more you have to worry about other metal objects in it's vicinity losing their molecular cohesion and collapsing (as Bran mentioned). You'd want to stay away from cars, bridges, planes, etc. without the proper containment.
