Artian Weapons

So im about HR 70 or so (i know dont judge me, my loved game is back)

Ive come to notice the “boom and popularity” of these artian weapons on videos/ through the people i play with.

I havent dove deep into them, but i have plenty of parts to do so if i ever wanted.

Are they like a must have level of strength? I absolutely despise the look of em, and would much rather use the crafted monster weapons as they look 10x better.
