I use both and like both depending on my recipe. I use honey with most of my oatmeal soaps, it seems to add more lather and mildness to them. I add about 2 teaspoons pp. I warm my honey so it incorporates easier at trace. I think it does make some soaps stickier and I have to leave them cure a little long by 2 weeks or so. I love honey in my soaps that I use goats milk in and any pureed fruits and veggies in like mango, carrots, applesauce, etc. I use sugar in soaps with any lard or tallow. For some reason the honey makes them not glide as nice, smells different to me also but then again my nose is shot from the FO's. I add both to some but i do not make it with any milks, or heater FO's. I see no difference in using both except I have to put them in the refrigerator so they will not over heat. I have not put the honey in my herbal soaps because I want to keep them vegan but have been thinking of experimenting with them also.
