I've narrowed it down to the two bcgs listed below in order to finish my build.
Nitride v2:

Bcg-x:

I'm curious as to which one would be the Better option. Is the bcg-x worth the extra $10.(nitride is currently out of stock) Would the nitride be more durable due to the c158 bolt? Is the nib-x coating more durable than the normal nib coating or will it eventually flake off with hard use?
I would just like some input on which of the two would be the better option, thanks.(the extra $10 dollars is not and issue,lol)
