Bottom feed is definitely a cleaner better taste experience. Be Careful though, the plastic tank separates from the metal ring that attaches to the bottom coil, so if you don't watch it, pulling it out of your pocket you will lose all the liquid. The design is flawed as the plastic tank doesn't even have threads, it just slips on and off the ring by pulling it. I lost a lot of liquid.
