Personally, I'm not too crazy about Virginia (from puresmoker). It's ok mixed w/french vanilla though. But man do I love the Cash eJuice Marlboro!!! It's my fav by far. It's not as harsh or peppery? as the Virginia. I think he's got the Marlboro in Pure Ejuice and the Cash eLiquid, and I haven't tried the Pure kind.
The Camel is ok. It's sweeter than the Marlboro and a bit lighter. There's something in it that bugs me though. Can't pinpoint the flavor. Maybe like incense? Sounds weird, but it sort of tastes like incense smells..
555 is very good! It's very nutty. It's almost like the Marlboro w/a nutty flavor added.
So, my opinion (in short)
Cash eLiquid Marlboro: awesome
Virginia: Peppery
Camel: Sweet, sort of incense taste
555: Nice taste. Very nutty
Hope that helps! My taste buds are probably shot from all the years of smoking, but that's the best I can describe it.
