I did an experiment today. I wrapped a bunch of coils. .9mmx.3mm rectangle wire 3mm id coming out right at .21ohms in dual coil configuration. I used the same mod set at 70 watts and same drip tip for all the RDAs in this experiment. All the RDAs have horizontal coils except for the Lucid RDA that has vertical coils. All were wicked with rayon. I used Vapetasia Pineapple Express 70vg/30pg 3mg juice in all of the RDAs. I wanted to see how all these RDAs compare to each other for flavor. I can't say I was surprised with the results. The results of this test are my OPINION. Your opinion might be different and that's ok. 1. Lucid RDA 2. Drop RDA 3. Cheetah 2 RDA 4. Mad Dog RDA 5. Battlestar RDA 6. Apocalypse / Apocalypse clone RDAs 7. Goon/Goon clone RDAs 8. Icon RDA 9. Rapture clone RDA 10. Goon 1.5 RDA 11. Glass cap Goon clone RDA 12. Radar RDA 13. Dead Rabbit RDA The Lucid has been my favorite since I got it. I think it is an amazing RDA. The I would not recommend the Lucid for a beginning builder though. The Drop is another amazing RDA. Arguably the best RDA on the market right now. Easy to build and great flavor/cloud production. The Cheetah 2 is another easy to build on RDA. Good for beginners and experienced alike. The Mad Dog has a tight build deck and is a bit tricky to build on but it's worth it. The Battlestar has a similar airflow to the Mad Dog. The Apocalypse is #3 on my list of favorite RDAs behind the Lucid and the Drop. There really isn't much difference between the authentic and the clone. The Goon and Goon clone are almost identical and are a good RDA. The Icon is another good all around RDA. The Rapture clone is not even close to the authentic but for $6 it's ok and it's a bottom airflow RDA. The Goon 1.5 is a cloud machine! Flavor isn't bad either. The glass cap Goon clone does much better with bigger coils and higher watts but it gets HOT and the airflow is just a bit too much. The Radar has a unique and easy to build deck. If you get the coil placement just right it's ok at best. I got the Radar with my Gbox but I would never recommend anyone buy one. Last and very least is the Dead Rabbit. It's garbage! The only good I can say about this POS is it is easy to build. Other than that it's a waste of money. No suprise there. I didn't include any of my single coil, 22mm RDAs or 30mm RDAs in this experiment. Like I said in the beginning THIS IS MY OPINION! It was fun and I won't have to do any building for awhile. I hope this was somewhat helpful. Also, for what it's worth, 1 through 7 are all good choices for flavorful RDAs. The Goon 1.5 is ok if you cut the airflow down but it really shines as a juice drinking fog machine.
