When I started this thread initially, the first rankings list was all vendors' juices except one: GoodEJuice's RY4. I had bought the RY4 concentrate that GoodEJuice sells, assuming that it was the same components and formulation that Nick, the owner of GoodEJuice, used to make his in-house juices. So, it was the one DIY RY4 that I included in the rankings, and it didn't fare too well.
Recently, Nick PM'd me to explain that the flavor concentrate was a pre-mix from his flavor supplier and not what he uses to fresh-mix his in-house RY4. He asked me to review his custom-made juice and later mailed me a 10ml sample bottle.
Nick is a very conscientious vendor. Here's a story worth sharing that testifies to his outstanding customer service: Some months ago, I bought a 30ml bottle of Nick's Tuscan Reserve cigar juice. When he changed the formula later, Nick mailed me a 15ml bottle of the new Tuscan formula---out-of-the-blue and for free---with a note saying that he didn't want me to vape anything less than his best efforts. Now, that's customer service.
My only quibble here is that I wish vendors would tell us when the flavor concentrates they sell are not the same as their mixed juices with the same names. Some vendors list concentrates by supplier---Lorann, Perfumer's Apprentice, FlavourArt, Capella, etc. But if they don't define the concentrate's source, how do we know what we're getting? We don't, and I don't like buying a pig in a poke.
All right, how is Nick's in-house, custom-mixed, freshly-made RY4? First off, it is indeed much better to my palate than the apparently generic RY4 flavor concentrate I reviewed initially. A week of steeping has helped its flavors to develop considerably. As a fresh-mixed-to-order juice, it was restrained and muted upon arrival, but now the flavors have bloomed and intensified. Deep rather than bright, this is an RY4 with some paradoxes: the tobacco presence is strong and central, but it's also caramel-rich, and thus sweeter than some. Despite having those distinct flavors, my overall impression is that of a well-blended harmony.
Is GoodEJuice RY4 superlative? No, not to my taste, but it is good. I like it better each day and now feel that, with more maturity, this is a very enjoyable RY4. The problem, however, is that "good" and "enjoyable" don't get a juice very far on this list, not with all the truly amazing juices clustered in the top half of the rankings. I don't feel that GoodEJuice trumps any of those, so it lands at #19, right between the two VaporStation offerings.
Please don't write it off, though. Like all of the Top 20 RY4s in this list, GoodEJuice RY4 is well worth having in your juice stash.
(Many thanks to Nick at GoodEJuice for providing me with a sample for review. He's definitely one of the good guys.)
