I personally love mine. In fact since I got it shortly after they were released, I literally have not used any of my other atties since. (Except when I melted my insulator, which was not due to anything faulty with the atomizer or insulator, but rather me shorting it out while trying to build beyond my limits
) I run the airflow wide open and love the draw. It's not as airy as, say, a Doge V2, but it is more airy (Is that grammatically correct?) than my Plumeveil V1.5 (Authentic).
Now, as far as leaking.... The well is pretty shallow, which doesn't particularly bother me, but it may bother some. Although even when I over drip, which is often enough, I don't experience ANY leaking, UNLESS I exhale through the atty first, which I rarely do personally.
Vapor production depends on far too many variable for me to comment on (Coil placement, the build itself, the
juice, how open you have the airflow, if you're using a drip tip or the chuff style it comes with, and if you're using it on a VW/VV mod, what voltage you're pushing to the
coils, there's probably more that I missed
)
The deck is a freaking dream to build on, I love it! I use the hex screws it comes with, but if that's not your style it comes with phillips screws. I really do enjoy this RDA if you can't tell haha.
My experiences I've posted about are all based on the authentic Dark Horse, not a clone. Just incase you're wondering.
Oh and to answer your original question. I used to run 22g super sub ohm Gplat builds on this little guy and the vapor production (Which at that point in my
vaping career is what I was going for) was quite, quite satisfying. I've calmed down a bit since then and still love it.
