I have the Drop Solo. For RDAs I have the Gorge, Recuve, Hadaly, Asmodus C4, Entheon, Pulse X, Loop, Oumier VLS, Gasmods GR1, and I think a few others I'm not remembering.
Out of all of those I'm using my Drop Solo so that's saying a lot!
The Hadaly has stronger flavor but I don't necessarily like it more. Sometimes it's too intense and brings out only one aspect of a juice in comparison to my Solo which I feel brings out the overall flavor more.
One of the reasons I like it so much is that I can chain vape without it getting hot. The airflow is pretty airy until you drop it down. I have it set to a third to half of the last set of holes and the last hole completely open. It's a good draw at that level. Very tight RLH. The flavor at that level is awesome.
I can get a very satisfying vape with the air closed down that much and flavor wise it's really good. There's several RDAs from that list that are about the same flavor wise but I just enjoy the fact that A. I can chain vape to my hearts content B. It squonks very well/a lot before you risk leakage and C. It looks really good on my Pulse X 90w.
The other reason I like it is because I always run spaced parallel coils (they're like zero spitback Clapton's without the power drainage) and it's way easier to build on than other RDAs I have. The other ones aren't difficult if you're doing Claptons, single round wire, etc but for parallel builds the clamp systems will have a hard time grabbing onto BOTH wires successfully. It becomes a headache that I'd rather not deal with.
