365 on my herbalaire.
I've found this all depends from vape to vape, most often vapes aren't dialed incorrectly so you'll be setting it at say 200 and it'll really be at 360!
with the herbalare I know for a fact that it's vaping at what temp it says it is, so 365 is the most ideal temp for getting lots of nice hits and getting hella high... maybe you might want to crank it up 20 more degrees to get some extra cannabinoids but in my experience 365 always did the job.
