One of the "Candle Shop" candles wow me, and I don't use paraffin. My favorite scented Soy candles are from Sentiments Soy Candles. They smell great and soy burns cleaner than paraffin.
Woodwick is hands down my favorite. You can't go wrong with sounding like you sitting in front of a crackling fire. Some of the other things I really like about them, they have never been worm burner for me (tunneling down the middle), the scent has lasted right through to the bottom, and it seems to take me forever to go through one. I burn mine usually every other day and for hours when I do. I have one right now sitting next to me that I have had for 1 1/2 months, burning every other day almost and there is still 1/3 left. To me that is well worth the cost, since they do run a bit high. Stacy
