Herters is definitely Tula ammo, at least in 7.62x39 (check the headstamp).
I thought it was a very thorough and fair evaluation, and the authors did a good discussion at the end. Yes, if you have to shoot the same barrel for 10K rounds with little or no cleaning, you want to be shooting brass-cased copper-jacketed ammo, but most of us will never put that many rounds downrange, and financially it may make perfect sense to shoot the cheap stuff.
I'd like to see the same comparison made with 7.62x39 to see if the lower velocity make a difference in barrel wear.
