I use a reaction rod to assemble because it is convenient and very flexible but for disassembly of an unknown build or stubborn barrel nut you are better off with an old school clam shell vise block or super reaction rod style that locks into the receiver as a regular reaction rod will put stress on the index pin, potentially shearing it off. Even then if the barrel nut is severely over-torqued or crusted on it may be required to Dremel cut off the barrel nut in order to save the upper.

have you ever stuck an upper in the deep freezer then let it heat up at room temp to loosen a barrel nut? lol the things we do

thats all i use! 1/8" 6013 at 90-130 amps or 3/32 at 80-110amps depending on material! my beads are much better with that than 6011!! ive welded some GRIMEY shizz with 6011 tho!!

lol dont get me started on 7018

Yep, but what you want do is take it out of the freezer and hit the barrel nut with a heat gun. Wouldn't work if it was loctited though.
