Asking this type of question in the Ask The Vets sub forum might not be as satisfying as just doing research into other threads and polls that already cover this. The adage goes "taste is subjective".

In this sub forum, one or two answers are all you might receive.
Let me ask you this, what are your favorite taste profiles? Tobaccos, fruits, desserts, beverages, menthol?
What PG/VG blends do you prefer? 100% PG, 100% VG, 50/50?
What's your budget? Getting by, or sky's-the-limit?
Today, you have about a thousand choices. When I started here a couple of years ago, I looked for the most talked about juices and bought sample packs or small orders. After about 20 or so vendors, I've narrowed it down to 3 favorites (Alien Vision, Good Life and FreedomSmokes USA), but am still looking at 2 or 3 vendors to try (Nicoticket, Ahlusion, Alice in Vapeland).
I prefer tobaccos, berries and desserts at 18mg strength in a 50/50 blend.
I don't know if this helped, but finding that one juice or vendor is all about the process. Good luck and reply if you are able to narrow in on what you are looking for.
