In general, I don't think price *necessarily* has anything to do with it. I mostly use CS, Peaks, GL, and NG. All companies have both very strong oils, and a couple oils that have been dissappointing in their strength and fragrance. As far as SW, I've only bought 3 fos from them, and they all smell awesome and are worth their price, IMO. In addition, they do have more complex fragrances to choose from. However, I've read where they've also got oils that are on the weaker side, or have been disappointing. For me, this has been discovered, well, very expensively lol. As Sliver said, you really have to try for yourself, and unfortunately it costs quite a bit of $$ to do so! The up side is that you *can* get ideas on where to start by searching/asking on this forum and others:) HTH~~and makes sense!
