I haven't tried the coffee flavors mentioned, but I, too, went on a search for something that I liked. I ended up with "Espresso Shot" from ECBlendflavors.com. I really didn't expect it to be very good as evidenced from the other coffee flavors I'd tried (from three different vendors), but I really like this one. I tried it just plain and I tried it with vanilla (no sweetener or "extra" flavor). Both are excellent. And, I use both in 6 mg nicotine and 0 mg nicotine. I just really like the flavor of the Espresso Shot. You can also get it with caramel, which I have not tried as caramel usually ends up being too "rich" for me, for lack of a better word. A 5ml sample of each with a 20% discount using the code 10020 is cheap to try.
