There's no one answer. It's all subjective and you're likely to to get as many answers as there are members of this forum. I believe you'll find that you may have to try a few before you settle on the one that's for you.
We'll need a few more questions answered so the you may receive a more informed response. Do you prefer flavor, clouds, or a mixture of both. Dual or single coil? What wattage do you currently prefer to vape? I think that you'll find (at least I have) that you'll get good vapes from lower wattage with rebuildables than with factory coil sub ohm tanks.
I prefer single coil vape with a mixture of flavor and clouds with flavor being a higher priority.
My current favorites for single coil are, in no particular order, Wasp Nano, Recurve, and Dead Rabbit SQ.
For dual coil, of which I only have a few, I'll suggest the Drop. The drop also functions very, very well in single coil. All of these are very beginner friendly with a lot of videos out there to help you along the way. I also have the CSMNT, Goon 1.5 and the original Dead Rabbit currently in the rotation. The Goon and CSMNT are both excellent drippers but in my opinion are ever so slightly more advanced. The dead rabbit is very nice with a large following, but I personally find it very finicky with getting the coils at the just right height.
Lastly, of the mods you mentioned I'd suggest using the Drag unless you just have to vape at 200+ watts.
So, this is just one guy's opinions. Good luck
