My personal opinion is the 50/50 liquid is more cigarette like because of the more pronounced throat hit. And higher PG liquid has more flavor. Higher PG=more flavor, thinner liquid Higher VG=more clouds, thicker liquid. Try the other e-liquids you bought. You'll have to experiment alot in the beginning to see what works for you. For me the higher nicotine level helped alot when trying to quit the smokes. I just quit smoking again after falling off the wagon for a month or two. I bought the Smoant S8, which uses the nic salt e-liquid. Much higher nicotine content, without the throat hit...or reduced throat hit. Let me tell you, it was the best purchase I made. When I'm really craving a cigarette, I grab the pod and poof! the craving goes away.
