Deep draws and flavoe? I would say the Tetrax, Solo or Crafty+ in my experience but since I got the Tetrax I can't wait to try the Stempod, Dreamwood and other 510 on demand vapes, because I want to see if all on demand vapes are that good or its just the Tetrax, because to me so far its the best experience I had with a portable vape and like it more than a bunch of desktop vapes I tried. About the Dynavap that I see a lot of ppl mention it, I think the Dyna is a must have for what it is, super portable and no need to charge it as it works with butane, I just love it and have it with me all the time, but, I would say the Dynavap is my least favorite vapor experience, flavor and smoothness, if I have any of my other portables around I wouldn't pick the Dyna unless I want to to a quick sesh, also I think the Dyna is my most breakable device, it's so so small and light that I constantly drop it (I was always clumsy with cigarettes when I was a smoker and now I'm clumsy with the Dyna), it's the only vape that I actually broke so far, dropped it and hit the ground with the cap and the experience was never the same again, had to get a new cap.
My 2 cents.
