I have both the Plume Veil and the Veritas. I definitely prefer the Plume Veil. I'm running them both on mech mods at .28 ohms.
Plume Veil:
Amazing airflow, for a cooler vape
Chucks clouds
Delrin insert helps produce amazing flavor when it's threaded down
Con: Can leak easily when overfilled
Veritas:
Great flavor (a little above Plume Veil in my opinion)
Less likely to leak if overfilled
Holds a good bit of liquid
Cons:
Vape is really warm
Awkward to build on
I ultimately agree with
jaxgator though. The Magma that I just picked up has been my go-to this whole week out of the three. Flavor is above almost everything I've fooled around with previously, clouds aren't AS big but it still makes a ton, and I can get around 20 big hits off of it instead of the usual 5-6 with my other drippers.
My recommendation is Magma, Plume Veil, then Veritas, though I don't think you'll be unhappy with any of those, no matter what you choose.
