Best: Virgin Vapor Organic Butter Cream Mint...so good and smooth.  Perfect balance of sweet soft creamy mint.  Only tried around 20-25 flavors, but this is really is good and my fav at the moment.
Worst:  Virgin Vapors Organic Best Damn Tobacco.  It's my second tobacco extract...the other tobacco I've had was Vaperites Organic VR4 which was really good (Honey Caramel-y Tobacco with a little doughiness or vanilla?)  Anyways, I'm not sure if other tobacco extracts are this way, but the one I received was very cloudy with little particles in it and a mucous-y green color that did not make it very appealing.  It kind of tasted like I was vaping cologne.  Tried adding some menthol to maybe mask the flavor, but didn't really help.
**I love Virgin Vapor juice, but I just really didn't like the tobacco.
