I have used 444 and 464 interchangeably for 4 years. I see a lot of complaints about both, but can't really understand why. I sell thousands and thousands of candles all year round and haven't had any issues. My tops are smooth with a single pour. 444 is a bit frostier than 464, but it doesn't stop anyone from purchasing and returning for more so I don't care if there's frosting. A great wax! It's HOT here, and I still sell year round at open air markets. The higher melt point of 444 is pretty awesome. 464 candles get beady pretty quickly, whereas candles made with a 50:50 blend of 464:444 hold up much better. Candles made with straight 444 wax hold up the best. Anyhoooo, great wax! Leaning towards using 444 exclusively.
