In my experience, the Aspire Atlantis tank chucks more clouds than the Kanger Subtank. That's because I prefer a cooler vape and the Subtank runs much hotter than the Atlantis, so I have to run the Subtank at a lower wattage than the Atlantis. The Atlantis 2, with a 0.3 ohm coil can be run at 70 watts easily. For flavor, the Subtank has an edge over the Atlantis.
