One thing to keep in mind other than how subjective taste is.....once you quite smoking, your tastebuds change. What you don't like now, you may very well like later...and vice versa. As for menthol vs non-menthol....there is no key there unfortunately. Hubby and I both were non menthol smokers....I like the
dessert vapes and 555 and RY4....hubby likes nothing but the fruits. Other former menthol smokers I know like menthol and some other
tobacco flavors that are non menthol. I also know former non-menthol smokers that like the menthols and mints....it's all very very personal and over time, favorites change.
It is fun however to see who all likes what, just be careful trying to make a scientific kinda conclusion to it, or trying to base what you will try based on it.
