Dekang is still the most sold eliquid in the world. There is nothing wrong with their liquid and they have a larger selection of flavors than most suppliers. All eliquid is purely subjective, a matter of what tastes good to the individual. Bad mouthing an eliquid makes little sense to me. I personally think Janty's RY4 is the best eliquid around. Others may hate it. Also, although I vape both PG and VG liquids, 100% PG liquids are far more popular (based on amount sold) than any form of VG liquids.
Another note: 24mg nicotine strength is the most widely used strength from polls on this and other sites. So I believe it is safe to say that the vast majority do not find it too strong or get sore throats or lungs or any other body part.
