The "BEST" of anything is what works for you to keep you from smoking. With that said I have over 100 different atomizers and there have been a couple improvements this year worth noting.
As far as I am concerned, Do It Yourself (DIY) is the best e-Liquid of all. You can save a ton of money over smoking tobacco products or buying pre-made e-Liquid to vape, infinitely control your nicotine concentration and control all your ingredients including flavors or not as the only and best risk management approach wrt e-Liquid.
In general, FlavourArt flavorings are the only ones that I know for a fact are performing relevant health testing and they are doing so in cooperation with an internationally renowned university. There are a lot of "labs" out there with all kinds of claims that are 100% USDA Choice Bovine Stool. I honestly believe the state of the art can be found at molecule labs. So in general any e-liquid line that uses FlavourArt flavorings and Molecule Labs is recommended. I also recommend simplistic labeling. The best labels IMHO do not have a cartoon or catchy phrase. A good label is plain and states what the flavor is along with the PG/VG ratio and nicotine content. Glass bottles with child proof caps are a must. The best bottles are brown or blue. For example Traditional Tobacco as opposed to Oh-Yeah cherry lemonade or AK-47. It's ok to have a company logo, but not an attempt at a copyright ripoff or a childs candy/snack/drink.
Unfortunates and what not to look for:
Everything else. Seriously I mean that. Until e-Liquid manufacturers advertise their ingredients (which they won't do and is one thing I would want the FDA to force them to do), you have no idea what junk they are putting in it. It may even taste great or have a cute copyright infringement ripoff packaging, logo or label. Those that at least advertise FlavourArt flavorings may be acceptable but that doesn't stop them from throwing in sweeteners or other junk that isn't in the FlavourArt flavorings. Here are some examples of piss poor, unprofessional, gimmicky, copyright rip-off e-Liquids that are proof positive that we need SOME regulation, just not the current one and another reason why DIY is better:
And so many more...
This is perhaps one of the most egregious and will ensure all by itself that the FDA will win:
Note the bottle is packaged in a pharmaceutical bottle. Note the refills and directions. Note to Bad Drip: No, you are going to suck on FDAs big stick. Morons.
Yes the FDA has hired people to scour the internet looking for this stuff so please look here. I am tired of these vendors and ...I use this word in the most loose fashion possible... "manufacturers" that are just in this to make a dollar without regard to intellectual property or health risks. Avoid crap like this at all costs.
I do not have an issue with people making money, even on the incredibly lucrative e-Liquid market. But it does matter HOW you do it. And if you have to resort to rip-offs and cute gimmicks then your product doesn't need to be sold.
