Seems like different people like different things as far as the actual juice delivery (atomizer device) system goes. Personally, I like carto tanks and feel they give the best flavor and most consistent performance with the least hassle. I hear dripping is even better, and while I"ve tried it on a small scale, it's not for me on a regular basis. Good for tasting juices or checking my DIY juice, though. I didn't have much luck with the clearomizer type things ...the tanks with wicks in them. Seemed to me like the flavor was tepid and they were just too fiddly for me...but LOTS of people do like them. Just depends on what will work for you.
I use most any sort of carto tank...Boge F16, Smoktech...whatever. But my new favorite is the polypro side fill Triple V tanks from ValleyVapes.
