Ocelot does excellent work helping vapors here on the forum. Major props to her.
I made a
picture dictionary of the more common juice delivery devices in this blog -

I also made a
cartotank setup guide with video demonstrations of the method that I have been successful with here -

In a nutshell, I've used both clearomizers, clearotanks, and cartotanks. I've preferred cartotanks for their better flavor production, durability, and once you get the methodology down their better consistancy and reliability. Having said that, current clearos have improved markedly in the year since I began vaping concerning consistancy and reliability, yet they are still a step behind in flavor production. Your results may vary.
Not particularly a fan of the
top coil/top wicked clearos, myself. I prefer a cooler vape, and the closer proximity of the heating coils to your mouth produces a warmer vapor which sometimes I find to be harsh. Additionally, top wicked clearos are fighting against gravity to feed the coils juice. You must frequently tip them horizontal or swirl the juice around in the tank to keep the wicks wet, or else you will get dry hits. Needing to remind myself to do this was annoying to me.
I've been impressed with the
bottom coil/bottom wicked clearos such as the Kanger Evod and ProTank. Cooler vapor due to a slightly longer distance for the vapor to travel, and since they are not fighting gravity, the wicks stay wet automatically so there's no need to tip or swirl. Not as consistant nor up to the flavor of a cartotank, but very close.
Clearos are undoubtedly easier to use and fill with juice. Basically just remove either the top (top coil) or bottom (bottom coil) to fill. Takes 1 minute or less. I chose clearos for my beginning vapor daughter's setup because these will be easier for her to fill for an on-the-go busy college student. I didn't believe she would have the patience to properly setup a cartotank. Changing the coil heads is also easy to learn.
Cartotanks do have a small learning curve. The most important part is properly pre-filling the cartomizer, and there are multiple ways to accomplish this to add to the confusion. Another perspective is, if one way doesn't work for you, there's another that might. It takes me 10 minutes to setup a new cartotank; 1 minute to refill a tank.
A cartotank can be re-filled with the same cartomizer multiple times. Expect the carto to last between 20 - 30 ml, perhaps less if the juice is dark in color or very thick (heavy vg). When the draw becomes stiff, it's time to replace the cartomizer with a new one.
