Ive had both experiences.
Some of the tobacco juices I have come to like, come from Mt Baker Vapor. I didnt like them at first, but they grew on me. The ones I like are semi-sweet tobaccos, but still not cloying or overly sweet.
RY4
555
Maple Rum
All three are smooth and rich, with no shortage of flavor. The RY4 mixed with some Maple Pecan or Hazelnut Spread is something I have vaped a whole lot of. And the 555 on its own is
Also, Fuzion has some serious flavor to their juices. Im not a big fan of fruit types, but Fuzion makes a few I just love.
Krankberry- If you cant taste this, your toungue is broken
Unicorn Blood
XTC
Roundhouse w/ Cream
All four are not only wonderfully delicious, but cant be mistaken. I actually had a bit of a hard time getting the flavor out of an Evod head or two with these.. I ended up just dedicating those heads to the juices.
Two hints that mayhelp-
1- switch flavors. Staying with one flavor tank after tank, will ruin your ability to taste it. And it will be a while before you can taste it again. I did that with a butterscotch. Its been about a month since Ive had it, and Im just starting to taste it again.. through an HH 357 Atty. It was so weird, it literally just disappeared on me, no flavor at all.
2- Drink lots of water.
3-Ok, and extra tip. Have some spicy food every now and then. I had a Wendys Spicy Chicken after about a week of
vaping, and later that night I noticed that, flavors I was
vaping earlier in the day, were crisper and brighter. Could be Im waking up the tastebuds, or clearing the sinuses, not sure.
