Cisco and IKV atties are always my favorite. With Cisco atties, they have a light draw along with good TH and vapor. The difference with IKV atties is that they have a slightly tighter draw to them. Depending on your preference with what type of draw you like. Will determine which brand will be the best fit for you.
The biggest advantage of these atomizers compared to other is that they don't come with primer. Which means that they are good to use out of the box. Performance wise, they are a tad bit better than other brands. Not by much in some instances. For example, Joye 510's is just about as good as a IKV 510 IMO.
So, that's my take on it. I'm not a fan of Bauways, Smoktech, Boges. Since they're performance and durability is sub-par compared to the ones that I have just mentioned. Really not worth describing all the reason on why I hate them.
