I agree that it all comes down to personal preference. I have used both and I prefer the Nautilus to the Subtank. Although since I have started doing lung hits more and more, I have tried using my Subtank again and now I do like it a lot more than when I first started using it. I still prefer the Nautilus, but at least now I am using the Subtank "right".
This is the most important post in this thread. The thing about these 2 tanks is they cannot be compared becuase they are 2 different types of tanks with 2 different types of coil heads.
The way I see it, to make it simple, there are 3 types of clearomizers...
- Low wattage vaping 11 watts or less (Aspire ETS, Kanger EVOD, Kanger Aerotanks, Any CE4/5 tank, etc)
- Medium wattage vaping (12-18 watts) (Aspire Nautilus)
- High wattage vaping (kanger Subtank (the Nano is a clearo whereas the others are considered RTA's) and any other sub-ohm tanks that are designed for 30W+ vaping - Kanger tanks with a 0.8 ohm dual coil head is not really a sub-ohm tank).
The nautilus is designed for mouth hitting (like a cigarettes) and the coil head (even the new ones with the cotton wicks and larger juice intake holes) is not designed for sub-ohm or high wattage vaping.
All the subtanks and their factory coil heads, even the Nano, are designed for lung hitting and sub-ohm vaping. Yes, I know they make 1.2 ohm coils, but the problem is the smallest airflow hole is too large to mouth hit. Even at 1.2 ohm, you still have to set the wattage up to well over 20W to get 5V. With the increased wattage to get the same vapor from the nautilus at 1.8 or 1.6 ohms, the vapor is MUCH hotter on the subtanks. Then, even if you set to say, half of the smallest airflow hole, there is too little air and this increases the vapor's temperature a little more. It simply was not designed for successful medium wattage vaping for the most part.
So they can't really be compared. It's like comparing an apple to an orange.
I love the nautilus but I would love to have more options for tanks like it.
