Strawberry Ripe is from TPA, even though it may say Fa on the bottle (that’s from Flavor Apprentice). FA is generally used for FlavourArt, don’t confuse both of them.
It’s always a good idea to let people know where you’re from and if you’re willing to pay for international shipping costs to get your flavors… Not all concentrates are available globally so with these questions, you’re bound to get suggestions that will cost you quite a lot to purchase.
Medecin Flower has some really good flavors that would fit what you’re looking for. They’re pretty expensive for a little bottle but if you look at the amounts you’re going to be using, you’ll see that the price per ml of e-liquid isn’t all that bad.
MF isn’t as easy to find as CAP or TPA, but if you look around a bit, you won’t have any problems buying your stash.
As Muth said, FlavourArt has some pretty realistic flavors, but that’s no rule for their whole line. Blackberry FA is (imo) one of the worst flavors, and not just from their brand. FA Lemon Sicily is a very nice and popular flavor but it fades pretty fast.
There are a whole lot of brands that have “good” flavors though. There are a whole lot of brands that have realistic flavors. But for example with strawberry… what is it you’re after? Are you looking for a ripe, sweet, juicy strawberry or one that is still a little bit green?
With these flavor concentrates, you get just one tiny slice of a flavor out of a whole wide range.
Compare it with colors if you like… what is a good color red? I can show you 1000’s of different colors red and what is going to decide which one is good or bad… There are all the different shades, leaning towards pink or orange or blue, some are darker and other lighter.
That’s the same way that you have dozens, 100’s or even 1000’s of flavors of 1 kind. Taste is so subjective and what I may like may be really disgusting to you.
If you’re looking for flavors, a good way to start is to open the flavor list and search for e.g. orange. Sort that list by recipes or rating, see which companies make those flavors, check the flavor notes to see what people say about them. Check the forums for flavor notes (there are quite a few if you use the search function).
And don’t limit yourself to ELR. There are lots of flavor reviews on other websites. If you shortlist a couple flavors, ask people about those specific flavors and how they’re used, look up recipes where they’re used and look at the comments people make on those recipes.
Taste is so incredibly subjective, nobody can give you a general answer about what is good, “the best” simply doesn’t exist and even if 100 people tell you a certain flavor is absolutely great, you may still think that it sucks.
The best thing you can do is to read, research and try. Take notes along the line.
