Genesis-style atomizers offer fantastic flavor when using steel mesh or ceramic, but the draw is too airy for me. I find it really unsatisfying, but wish I didn't because the flavor is great.
For something with capacity, I like bottom-coil atomizers like the
GP Spheroid and Kayfun Lite. Dripping can be a pain, but once you get accustomed to it, it's no biggie. Plus, you can see when you coils need a dry burn or replacing. Some full-time drippers feel that
juice delivery systems with capacity can alter flavor, since the
juice is constantly being heated, cooled down, and reheated. I haven't noticed that myself, but I suppose it varies from
juice to juice.
