It is mostly agreed upon that V2 Cigs would be the best current electronic cigarette on the market. The vapor clouds it can generate are incredible and the feeling the throat hit provides is just the right blend of harsh and soothing. It does not overpower like some can.
The overall variety offered by this electronic cigarette is also truly remarkable. Just as you would expect, there are tons of flavors with the V2, but it goes even further even down to designer batteries. The growing trend of e cigs as a more fashion oriented accessory can be catered to wonderfully here. The design is forward thinking in other ways as well, such as the inclusion of the new EX cartridges that last twice as long as before and allow the user to see how much liquid they have left as well.
After the V2, the Green Smoke model is likely the next best choice. Users actually tend to flip flop on which they think is truly best. The Green Smoke provides a great flavor, large potential exhales, and perhaps the strongest throat hit found in any other variety on the market. It is strong, but of course, there are plenty of vapers out there that will enjoy that. If you smoked lighter cigarettes before however this will not be for you.
There is also quite a bit of bite upon inhaling as well. Full flavored cigarette users of the past (or heavy smokers in general) will truly love the Green Smoke. The vapor clouds are about on part with those provided by the V2. It also helps that their menthol ice flavor is about the best version of menthol found anywhere else. Green Smoke is definitely a solid choice overall.
Next, potential vape users may want to consider the South Beach Smoke electronic cigarette brand. This brand does not have much of an effective throat hit, so previous smokers who liked light cigarettes will probably enjoy it. The smoothness might be a bit too dull for others, so your mileage will vary. It is a fine choice other than that.
However, the Premium Vapes brand offers the same smooth effect while also providing much more choices. This may be a good choice even for anyone simply to help keep usage interesting. Since using e cigs are a way to get off of more dangerous regular cigarettes, anything to help inspire you to keep using the electronic variety instead is a plus. There are also plenty of aesthetic choices to choose from with this brand. They certainly know how to turn heads.
Ultimately, the Simply eLiquid, Premium Vapes, Green Smoke, V2, and South Beach Smoke varieties are all strong contenders and might be all you will ever need out of an electronic cigarette depending on personal taste. If you like strong throat hits, by all means, go for the Green Smoke, and if you like it smoother, the South Beach Smoke is best. The V2 is the best at combining both worlds however, so it would make a great first choice.
