Alot of it depends on your vapor temperature and air draw preferences. For a tighter draw, the Nautilus Mini at 15-ish watts is tough to beat. For something a bit airier, the newer GS Air M and GS Air MS really rock... again, 15-ish watts. For a really loose airflow, you'll need to go to a sub ohm tank. Then, the answer really broadens. So far, the three tanks I've used with the best flavor are the Freemax Starre (also called the Vapeston Maganus), the High Voltage, and the Atlantis V2. Keep in mind, these are all with the 0.2 to 0.3 coils and TONS of wattage. They're all close to a dripping experience, but not QUITE there. Hot vapor, though.
