For those who use toilet paper charcoal for black powder

What are the best and worst performing ones? Is toilet paper generally a good charcoal for black powder even if its a shitty performing one? I know everything black powder has tried a few but any brand be a pretty decent charcoal or should I just stick with cottonelle? I am trying to branch out of using my first charcoals and I want to use toilet paper just to fuck around with.
