I'm pretty new to this also but I will give you my 2 cents worth. I use the J223 and love it. It is a one pour wax, my candles are always nice and smooth, and scent throw seems to be good with this one. Very easy to use IMO. I also use EZsoy. I get an awesome cold/hot throw with almost all of my fo's with this one. I would say the throw almost doubles compared to the J223. This is a one pour for me too. The only downfall with this one is that I cannot get a good looking top, which I know this is characteristic of soy. And sometimes after the candle burns, it is so scaaary looking! Looks like a bowl of colored cauliflower. I also let the soy cure for 1 week and the J223 just one day. HTH!
