Personally I prefer the Cargill C1 to the Cargill C3. The C3 is inconsistent (Cargill is still tweaking it), it's greasy and harder to wick, and the scent throw is only slightly better if at all than the C1. The C1 is comparable to EcoSoya CB135. Haven't tried the PureSoy or Advanced. But based on the description, I'd try the Advanced. Don't care for the GB or GW. Working with soy always ends up being individual preference. As you find something that works for you, you always learn to tweak it for best results. Find something that is readily available, that has a good reputation for not changing too much from year to year, and that you can learn to pour with the least worry and effort. Hope that helps!
