I'm a blanks and juice guy myself, and most of the flavors are so personal preference based...but there are a few that I find to perfectly match their namesake - in other words, not too weak, no odd other-taste, and doesn't taste like something of another name.
For example, I like each of these juices alright, they're not bad, but for me they are a bit off:
Wow Caramel - a bit on the weak side
Wow Sour Cherry & Cherry Cordial - the cherry carries a bit of a chapstick "other-taste"
Wow Pina Colada - tastes like a wrong name to me, should be Squirt Soda imo...pina colada should play well with coconut, this does not
*Wow Pineapple - [was] a perfectly delicious pineapple upside-down cake, not a fresh pineapple (go Premium for that)
Wow Pancake - what's this?
I find these to be spot on, if you like the name you will like the flavor:
*Wow Cola
*Wow Melon
Wow Waffle
*Wow Butterscotch (hard candy)
I also really like:
*Premium Cognac (hard to describe, if you like Cola vapes, you'll probably like this)
*Premium Bananas Foster (on the creamy sweet and light end of things)
Wow 555 (honey-nutty, Premium 555 is much more grassy-tobacco imo)
I put a * next to the ones that are my current favorite V4L vapes. They seem to change you know.
