Well, I can compare the Octanes to Halo. Halo flavors have a heaviness to them and a tad too strong on the flavoring. Octanes are well blended, very well blended. And Octanes have a cleaner, truer taste. These are spot on tobacco flavors. Cigarillo is a much smoother all day vape than Freedom. It is full flavored tobacco and fantastic. In fact I love Cigarillo. I don't go a day without it. Signature is what Torque tried to be. It tastes exactly like a fresh pack of premium cigs smells like when you first open it (if that makes sense). Plain tobacco is a lighter version of Cigarillo to me, like a light cig. I haven't tried it but I would imagine that SpiceBacco would be similar (but better than Smooth 8) based on my experience comparing the two lines.
These liquids are so spot on that people are starting to doubt that I'm using ecigs because they smell tobacco and see incredible thick vapor. I had to laugh because when I went to visit my son (a kr808 user), he was watching me vape in his apartment. He was watching the thick vapor linger in the air and said "Wait a minute. Are these still ecigs. Is that smoke? Will it stain anything? Are you using tobacco somehow?" I had to remind him that We vape! Yes, I vape still, like he does, and no it's not tobacco - but Great stuff isn't it! I then asked him if he was sure he wanted to stick to those kr808's and China juice. He just said, "When I use mine I don't get vapor like that." I laughed.
