I've run the Quasar, Helios, Magma and Veritas RDAs and while I originally favored the Magma, I'm now leaning toward the Veritas as my new favorite for flavor and clouds.
The Magma puts out some good flavor, but I've found the downside to that RDA. After building several coils, the negative post starts to spin when tightening the screws. When it initially started, I just grabbed the post with a pair of needlenose pliers and held it while I tightened the screw. I went out and bought another Magma because I did like it so much, and the other one started dong the same thing. I talked to my local B&M and before I could even tell him what my issue was, he called it. Spinning posts. Apparently it's an issue with all of them, clone or authentic. I actually had the negative post completely pop out of the first Magma last week when I was trying to adjust my coil. I was able to put it back in and it seems ok, but it's annoying all the same.
The Veritas I picked up is kicking some serious flavor and clouds. It's a little tougher to build on, but it chucks. And another bonus, no leaking... So, the Veritas has my vote ATM. YMMV.
