This is my first post (Hi all)!
This list is longer than just my best, but these are the ones I have sampled in the week I have been using a VaporKing (yes, I have spent quite a chunk of change this last week, I'm sure Steve and Mark and everyone is quite happy

).
Excellent carts:
Chocolate Banana - Excellent blend very close to shakes / snacks I have had in the past. This is my staple "all the time" cart which I use with 0 mg nicotine and switch out with other heavier tastes with nicotine content (listed below).
Cognac - Rich, hits nice, great flavor, and interesting conversation piece. I have only had one cart so far (free samples are great!), but have since bought a bottle and 5 carts for this flavor (need to get bigger than 5ml bottles of this one in stock please!).
Red Cow - Tastes just like the drink, though at first I didn't make the connection and thought I got a bad cartomizer until I realized the flavor it was supposed to be.(LOL)
555 - No idea if it tastes like the original smoke, but this makes a great strong flavor to keep on hand for steep cravings or adrenaline rushes (I also use with higher than usual nicotine content). It just leaves me satisfied when I need that bit of punch.
Cowboy - This flavor seems to be unique to the V4L / PV market as i don't find it tastes anything like a Marlboro. Rather it tastes like a rich nutty/woody/ dark chocolate... Excellent flavor, and the corner staple of my new habit.
Peanut Butter Cup - Great taste, IF you don't expect it to taste like a specific brand of peanut butter cups (it's close, but not quite). (I have only tried 0 mg in this one so far though.)
Decent carts (might get again)
Irish Cream - Nice flavor (sort of weak on the hit on mine though)
Cappuccino - Good flavor and decent hit but went from great to horrid at the end of the juice almost immediately with no warning (bad cart?).
Lager - Ok flavor, very rich and deep but was too subtle for my tastes. Didn't get much vapor from it.
Milk Chocolate - Ok flavor, certainly not a very intense chocolate taste. I'm a dark chocolate sort of guy though so I don't think I'm a good judge of milk chocolate. Would suggest to someone who isn't as into the rich and dark tastes as I go for. I'm probably going to stick to chocolate banana or maybe try the Dark Chocolate...
Not my style:
Pear - Ok, this one didn't taste like much of anything, but what it reminded me of wasn't pear... it was too airy and sour for pears (maybe a bad cart, only had one as a sampler).
Rootbeer - Couldn't really taste it at all. What little I could taste was almost a sensation like only getting the carbonated air from the bottom of an empty soda cup with lid through a straw. (It was another sampler, who knows?)
VG Style Cartomizers - I picked these up because I got a nasty sore throat the first couple of days thinking I was having a PG reaction. I found out that it was because of a crappy unit I was still using along with the VK for a while which required too much "sucking" to activate (was nauseous for days). That one has been donated to someone else for the time being who doesn't mind the rather difficult experience (yet)... The draw through the mouth is cooler than with PG (very airy) and the throat hit seemed to not exist at all (in a low nicotine VG to PG comparison). There was a very "flat" sensation to the vapor which seemed similar to particulate smoke with little moisture in it. Some say it is very sweet, but the flavor seemed muted to me. Lots and lots of vapor on an easy draw which hung around longer than PG though. If you are a visual smoker this one might be for you! If you expect to feel the vapor colliding with the back of your mouth / throat / lungs on the way down (without direct inhaling) this will not be your treat unless you really do have a PG allergy.
All in all I think the free samples (tossed in with my orders) was the best idea as it really got me introduced to quite a few flavors without my having to make a $11 investment to find out I don't like them 1 pull in. I am quickly becoming Customer4Life due to the service I have gotten @ V4L.
