Why is Kanger subtank mini much more harsh than my herakles tank?

if it's a vertical coil, i guess it's harder to see if the cotton is burnt.

I looked in with flash light and magnifier glasses. can't see anything that looks burnt, seems like cotton is intact

I replaced coil, and it seems to be better, but still have to vape on lower wattage, and draw very hard and fast. It seems to produce a larger/warmer cloud at lower wattage than Herakles. I guess the Herakles is just a smoother, less harsh draw than Kanger. I highly recommend the Herakles for sub ohm! Thanx for all your input.
