The stick is superior to roughing fluids in my opinion. There's less pressure to apply evenly, and can be used to partially rough much more easily than a fluid.
And in this case, it's much better than others on the market. It'll also probably last you a lifetime.
In terms of the performance I find it the most similar to the widely produced decks (if you get what I mean), and you can change the sensitivity depending on application. After a little messing around you can find your perfect touch.
