I never compared them. Once I started powder coating I haven’t lubed a bullet with the lubrisizer since. When I was lubing them I only shot cast bullets in pistols and I’m probably not a good enough shot to tell the difference. Now 95% of my shooting is rifles and I have no desire to shoot lubed bullets in them. The pc’d bullets are much cleaner to handle and load, little or no smoke when shooting them and the guns are much cleaner.
I’ve thought about comparing them but don’t know if I want the mess again. If I do, I’d probably use the Lee lube and try it with and without powder coating. I’d probably be mad if the lubed bullets shot better than pc, then I’d have to deal with the mess… :-)
