I get simplicity. I feel the same way about the ubertoot, I've had 3, kept one and still use it. no jfc (well not one that can be adjusted from the outside) you have to take the tank off to fill but it works well & it's easy, you can literally pour juice in & never any seepage, let's you cut the wicks super short, and some of the densest vapor and best flavor I've had. Never any leaking unless I'm on a flight, always wicks well and always works flawlessly in TC. It's also got the perfect draw all the way open that I like which is hard to find, like a restricted lung hit but more on the mtl side.
