In my search for my first upper build, I see BCM has a different stainless for their SPR barrels. How does it compare to the usual 416R stainless barrels?

BCM makes good stuff, but there are so many quality barrels to choose from that a more specific question would help. I recently built two rifles with Wilson Combat and Black Hole Weaponry barrels, and both have impressed me. But there are more experienced individuals on here to chime in.
 
Specifically BCM claims their barrels wear better and are more corrosion resistant. Increased wear is nice. I’m not concerned with corrosion resistance. I would assume accuracy is comparable to other barrels intended for SPR/DMR builds.
 
My BCM stainless barrel will run right along my buddies Rainier Supermatch barrels. I can routinely get .75 inch groups with 77 and 69 grain match loads. Anything much over 1 inch with quality match ammo is definitely me messing up. I've shot a few .5 inch groups, but it's average is probably around .8 to .9 inches at 100 yards.

It also shoots decent 55 grain ball under 2 MOA. I actually use 55 grain ball in my BCM SPR out to 600 yards regularly.

Like others have said there are a good number of high quality match AR barrels. If I was going for the best shooting rifle I could build, Id look at one of the barrel manufacturers like Kreiger, Bartlein, WOA, Doiglas, etc... but the BCM will shoot well.
 
I was mainly wondering if the different material made any difference. It’s not wildly different but could be longer lasting, even if only 10% more. I’m currently also considering WOA and Roscoe. I’ll check Black Hole too.
 
Basically 410 stainless steel is a bit more corrosion resistant than 416R stainless steel. 416R has a higher sulphur content than 410.

My experience with both is as a machinist/tool and die maker using both in industrial settings. I'll let the barrel experts chime in on which is better for rifle barrels.
