Flavour wise I prefer the Artic, which I find produces a cleaner taste. However I do find myself going back to the Atlantis 2 when I want a nice hot flavoursome vape. Fires well at 75/80w, and the air holes in the drip tip really work to add in more airflow and keep the mouthpiece cool.
Build quality is simply the best, no leaks, easy to keep clean and robust. It's definitely one to have in your arsenal. It makes the original Altantis redundant.
