Taste is subjective, so only you can find what you like. Note that just because you like to ingest a flavor doesn't mean you will like vaping it. IOW, when I first started doing DIY about 5 years ago I bought a lot of flavor profiles that never got past the initial try or were never used at all. Right away the fruits, bakery, dessert, candy, etc... IE overly sweet vapes were a fail for me, and still are.
The suggestions from others to try some pre made samples may shorten the hunt and save you some money. But I found that almost none of the pre made juices I tried could ever be a regular in my rotations, and those few were replaced by my DIY. My DIY's became my perfect vapes, so I haven't bought any pre made joose for well over 3.5 years. I was sent samples of 6 pre mades from ZAR a couple of years ago to try out... in the end only one scored. But I never bought any of it, instead I DIY'd my own similar version of it until I got tired of it.
