If you're looking for that pure "cigarette" taste, you might try Freedom Smoke USA's PureCig. Personally, I used to smoke Parliament Lights. I started out with V2's "Parliament" flavor and it was okay. Certainly nothing like the analog flavor, but it was good enough to get me off of them. I then moved over to V4L's 555 and ordered a big bottle of their Parliament. By the time I got it, I was done with the cigarette-like flavors. That bottle of V4L Parliament fluid just tasted like acrid smoke. Eww.
Now I'm vaping mostly fruity flavored stuff. My current favorite is FSUSA's VooDoo, but I also like their Tranquil and Tutti Fruiti and VapeRite's Champagne. I have a few other juices I'm steeping, and a fair amount of previous favorites Wyatt Earp, Rocking Chair, Cocoa, and RY4 that I got tired of. However I suspect I'll get tired of my current fruity-flavored juices in a few weeks so I'm keeping those others around to go back to if and when that happens.
The best advice I can give is twofold -- buy lots and lots of small samples from many places, and don't be afraid to branch out. A month and a half ago when I first started vaping I never would've tried a juice described as "a mysteriously fruity vape with a dark undertone", but a few weeks later I bought a 5ml bottle and really enjoyed it. Of course once I realized I liked it and needed more it went on backorder

. Just got a 30mL bottle in the mail today after ordering 2 weeks ago.
