Is there any kind of compiled list of best flavor for brands?
Not that I know of, Siva, because taste is so subjective to each individual's preferences. It's similar to asking everyone their real life coffee preference.
Today, I am enjoying the heck out of Vapor God's Peanut Butter with a couple drops of their Ripe Banana. Totally a childhood favorite of mine and recreated spectacularly by Vapor God!
