Some of my top rdas are the Glacier v1- because of the airflow and super deep juice well. Velocity-by Avid I personally enjoy the flavor off this rda...i usually close the top airflow halfway and side a little over half(nice short drip tip makes it even better) . The Buddha 23 is my newest and a very durable rda with no limit to builds or airflow. Kennedy comp authentic - pretty good flavor. 13 Heavens by compvape is a builders dream and a very versatile rda. This is my opinion on this because I enjoy a combo of flavor, clouds and I love to build! Last but not least the Phenotype L by Anarchist mfg and Aria just because it's ridiculous.
