Some of my current faves that see everyday use:
Basic 1.1 (pretty restricted, incredible flavor and leak proof)
Alcatraz (very smooth, hadaly-like draw, but doesn't leak - also vertical coil)
Armor 1.0 or 2 (both good and versatile)
Hellfire Strike, Hellfire Sentinel (both solid designs with good airflow and flavor)
Mulciber (another versatile rda that supports a wide range of builds. It is older but the design is solid so it stays in my rotation because it is awesome)
Jorda B (smooth, quiet draw but pretty testricted)
O-atty v1 (another older one but nice and airy for when I want that)
My two absolute favorites right now are the skyfall and convergent rdas. They have the best balance of smooth, quiet and flavorful vape I've had yet. Skyfall uses swapable air disks to change your airflow, the convergent also has swapable air inserts but the default one it comes with is very restricted. The others have to be ordered separately. I odered some but I will probably just keep using the default until I can buy another convergent to try them with.
The airiest attys out of those would be the O Atty and Hellfire Sentinel. The most restricted would be the Jorda B and Convergent.
Most flavorful would be convergent, skyfall, basic and mulciber
Everything else I have including my hadalys and entheon are not being used right now - only have so many mods I can put these things on [emoji2]
