There are so many possibilites and combinations of juice, atty, cart, low & high resistance, voltage, etc. that is almost impossible to come up with recommendation, especially when one adds the biggest variable of all: our individual tastes and preferences.
In roughly 35 years of analoges, I stuck to Marlboro Reds and only tried other brands when I could not get them (used to travel a lot internationally for work). In roughly 8 months of vaping, I have changed direction at least a dozen times.
Now, I vape at both 3.7 and higher voltage depending on the juice I am vaping. I find the fruit flavors just do not taste at the higher voltages, whereas the chocolate/coffe/cake flavors at best at around 4.5 v, and the tobacco at 5v and above. But that is my taste.
I find myself best served by a variable voltage unit since it will always adapt to my needs. Especially now with the chance to run two batteries in series at 900 mAh, you can also get decent duration of your vaping device.
There are a lot of choices out there with more arriving every day. I use a Buzz and Big Brother which are good units if you want varialble voltage. I tried the Joker AV, and it sucked absolutely as did Vaprlife's customer service. It took them 6 days to get an answer back to me for a unit which was defective on arrival, at which point I decided to return it after getting lip from Vaprlife's customer service. Cost me $40 for restocking and extra postage because they only gave me 3 days to have the defective unit back in their hands from the moment I got a return authorization.
