Current favorite flavor RDA's:
Atomic Dripper no doubt about it! This little thing is a flavor beast that puts out dense clouds. Only problem is, it is a "little" beast that puts out dense clouds( Constant re-dripping) Amazing build quality. Tiny little deck isn't the easiest for chubby fingers or newbies to build on. My favorite atty for trying new flavors.
Vapewell 26650 RDA- What??? A 26650 RDA on a best flavor RDA list. Hell yes! Airflow comes in underneath heat sink fins down the side of the dripper and the out onto the coils. Over drip to your hearts content because it will just run into back into the air channels. I have actually filled juice over the coils and never leaked a drop. LOVE this feature. Deck is actually a 22mm deck because of how the airflow works, causing this dripper to have a super reduced chamber and amazeball flavor. Unbelievably happy with this RDA. Looks, performance and function all top notch. A little innovation goes a long way.
Surric Galaxy- Made in Southern California. Super reduced chamber for a dense warm flavorful vape. Tellurium coated center pin makes this RDA hit extremely hard. Very basic easy to build on deck. Really nice craftsmanship. Beautiful, deep engraving. Non adjustable airflow is a bummer but the stock holes are absolutely perfect for me. If you like a mouth to lung hit this RDA is not for you.
Magma- This dripper has been talked about a lot in this thread all ready so I wont go into too much detail. Air from directly below the coil, and the chamber shape combine to make an amazing moist flavorful vape. Very kayfun like in flavor. Super newb friendly with its dual post design, making it extremely easy to build and wick. It holds a lot of juice in its well but will leak like a well used whore if you don't juice it correctly......lol
Current favorite cloud blowing RDA's:
Mutation X (v1,1.5, or v2) and Mutation XL- What's not to like. This dripper designed in the US by Chris Essker and made in China originally by Unicig has now been cloned by almost every Chinese manufacturer. Most of the factories are making damn good versions. Tons of really controllable airflow, huge post holes, DEEP wells and a large build deck, make this a cloud blowers dream. Is there such thing as too much airflow? I think not. I use these drippers a lot.
Big Buddha RDA- Totally awesome 26650 version of the Plum Veil . Mega airflow options including air from the negative post to hit the back of your coils, Cyclops style airflow to hit your coils from the front, and air from the top if needed for extra cloud density. Another BIG RDA with awesome clouds and acceptable flavor.
454 Big Block- Not easy at all to build on but once setup correctly capable of really nice clouds and wonderful flavor. An affordable easy to obtain US made RDA. You would think something must be wrong, but its a kick ass well designed product.
I am sure there are better in both categories but I have had the opportunity to use and own a bunch of RDA's and these are my current favorites.
