Welcome to the community (from a fellow new joiner). I too have found that there are TONS of useful information here and an overwhelming number of friendly and helpful people on this site. I guess it all has to do with our shared enjoyment and hobby.
Juice selection is such a wide open topic, I don't think that anyone could suggest their own preferences and have them perfectly match up with yours. Just like craft beers, and small batch whiskey, taste is all about discovering what you like.
If you are fortunate enough to have a vendor/shop near you (or multiples) many of them will offer a wide variety of juices, brands, flavors to choose from and many will have the ability for you to test sample and better learn/understand/express your own preferences.
With that said, there is also a lot to be learned from browsing the online sites and reading the juice reviews. People will (generally) be honest and frank with what they liked or disliked about a particular juice, and if you find a particular offering where the reviews have sounded of interest, you can look into whether or not the vendor offers small bottle "sample packs" usually 3-5 ml bottles in a collection. They want your business and so some will make the extra effort to collect and package a small bottle sampler for you.
Sooner or later though, you will find a shelf or cupboard in your house full of bottles that were "nice tries but not something you're going to buy again". It's the nature of the beast. But experimenting, hunting and searching for that perfect "all day" or "special craving" juice is part of the fun of this hobby.
Myself, I spent some time exploring the JohnsonCreek site and getting their samples, some of which I am now buying in 30ml bottles and enjoy to this day. It allowed me to find what tastes, sweetness, TH, nicotine levels, PG/VG mixes worked best for me and now I can visit other sites and make even more informed decisions about their offerings based on how I now read their reviews with a little more knowledge under my belt.
Best of luck in your search, and may you find the journey as enjoyable as the final goal.
