Taste is highly subjective, as well as depends on what ratio or strenght of nic you get, or extra shots.
I would suggest just getting lots of samples where you can, and find what you like.
What have you gotten that you like? Then people that like the same thing will help you find others that you might like.
Of course, what they like, you might not, so again, until you try them, you won't know.
What sort of flavors do you like?
