The problem with many eliquids is that they were created by average “cooks“ using average (or the cheapest) ingredients. Think of it this way. You likely have many restaurants in the town or city that you live in. Think of the worst ones. They may create flavorless or overcooked dishes. They cook the dish too long, or too little. Some use cheap ingredients, or too much/too little of an ingredient. In short, there are 5 star restaurants and 1 star restaurants. The same is true with eliquid manufacturers.
