Some do work better than others.
Currently using KG1 for carbon and Bore Tech C+2 for copper. Wipeout has worked well in the past after overnight soaks.
As has been mentioned, HBN coated bullets reduce copper fouling, such that the copper cleaning products aren't used very often. I mostly use them to protect the bore from corrosion during storage, as very little copper collects. But I think a dry bore stored for months on end in the gun room poses a corrosion risk. Which means I never use ammonia containing products any longer. Gave them away.
