I've had a good vanilla and a slightly BBQ vanilla too, along with a slightly BBQ juicy peach. Maybe its the flavors you've been trying. I've never had kiwi or blueberry so I cant vouch for there flavor. I can say that it sounds like Watermelon, Cooling, Juicy Peach, and Vanilla have a bad BBQ taste to them a good amount of the time. So be careful when purchasing those flavors because you may end up with BBQ.
Try some chocolate mint or lemon NOIR sambooka and then tell me you don't like tangiers.
