The main difference is how the nicotine hits. SaltNic delivers a smoother throat feel even at higher levels, while freebase gives a sharper hit and is better for bigger clouds at lower strengths. Dymok carries both types of e-liquids as part of their full line of smoking and vaping products, so you can compare based on how you like to vape — fast and discreet, or slow with bigger clouds. It really depends on your device and how you prefer your sessions to feel.
