No e-liquid tastes exactly like an analog. Most of us wouldn't want it to. [Have you tried to smoke an analog recently? Yuck! <-- spoken by a man who smoked for 40 years.]
Many of us enjoy a good, rich tobacco taste, but opinions differ on which e-liquid flavor/supplier delivers it most effectively. I've read raves about Halo's Freedom and Harley juices, NHaler's various tobacco flavors*, LiquidXpress' Honey Flue Cured, etc. [I'm sure many ECFers would scream at my omissions: confirming that there are many worthy contenders out there.] I happen to like regular old DeKang or Boge "Marlboro" (however it is deliberately misspelled), although DK-TAB and Cuban Cigar are pretty neat too.
* The NHaler ones I've tried all taste (to me) like tobacco with almonds or hazelnut, to varying degrees. Since I am cheap, I've not tried the Halo or LiquidXpress juices. I probably should try Viking Vapor's Signature Series (e.g., Cherry, Apple, or Hickory Smoke Tobacco). AllAboutTheVapor has praised them and they are quite inexpensive.
If I were into DIY, I'd try experimenting with the various FlavourArt tobacco flavors. I've read good things about them. But, in addition to being cheap, I also am lazy.
The point to all this is that you need to explore for yourself,
guided by others' reviews, but expecting that your taste may differ. And be aware that your tastes probably will change/evolve over time. [For example, I don't like RY4 nearly as much as I used to.] All part of the excitement of the wonderful world of vaping, so to speak.
