My opinion is when the Arctic is right, its really right. Not much harshness for the amount of cloud it produces at various wattages. And while it drinks juice, its not as much as a tfv4 or even a Crown.
Now for the negatives. Air flow does not lock, it fills from bottom, smaller capacity, glass does not swap out. All minor considering the reasonable price.
Heres where I struggle with Arctic. Given the cool comfortable vape, I will take long slow drags like with an analog. Very easy to burn out my 0.5 coils doing this, even at lower watts. Not sure if it goes in drawer or I buy more coils.......
For comparison, my Herakles is a warmer harsher vape. Using it in the car is out of the question, unlike the Arctic. Bigger clouds, and the coils do last. My throat prefers the Arctic as the daily driver though.
Either has better taste than Atlantis V2, which is not terrible with the 0.3. The Crown coils are too hit and miss for me at least. Have not tried Starre Pro but many good reviews. TFV4 over the top for me, but probably the king at the moment.
