I have a Kayfun Lite + and a brass Kraken, I will also include the Taifun GT since it's one of my favorite toppers. So, of the three I like my Taifun best. It is super easy to build and with a micro coil and cotton wick the flavor is great. My Kayfun for some reason seems a bit fussier and the flavor is not the best out of the three. I have a chimney coil wrapped with cotton wick on the Kayfun and it wicks nicely, blows good vapor but flavor could be better. The Kraken is a genesis style atty, so there is a learning curve for setting it up. I have a dual micro coil set up and I have wicked with cotton, which is good, but now I wick with XC-116 which is a ceramic wick that's pliable like silica and that is fantastic for flavor and much easier to build with. To be totally honest I got the Kraken in order to match a brass mod, but I'm loving the experience.
