I have only tried a couple of others, however, I am not 100 percent on what kind they were. I will say this. If you can get the ones that have the wicks that float all the way to the bottom, I like those the best. They do sell them at vapage, and they are the clear variety.
Sorry I can't be of more help, but I am still a newbie!
But as far as vapor production and durability, these are pretty sweet
