I'm a vape/pod junkie. I have 3-4 mods and 7-8 pods. It's ridiculous, really. But to answer the question I have two favorites and they are the ZERO and the SUORIN. The ZERO's drag is a bit easier than all the others I've tried.
I have a *terrible* time getting any flavor from my juice (no matter what flavor or brand) and spent *way* to much money desperate for a pod that I could taste from. Finally it clicked what people were trying to tell me (in totally techy geeky terms) and that is a pod doesn't get hot enough to generate the flavor. I found that I don't get any flavor until I get up to vaping at like 90.
Hope that helps.
