All are decent but not great.. It depends on how much you're willing to spend, portability or home use, how often you vape.
I think Arizer has that deal were you buy one get one free... they may not have it anymore buy now but would be worth looking into...
Yeah I believe that deal is still going on at Arizer.com You get a free silver Air with purchase of any vape. You can always sell one to pay for one or use both for certain situations. I myself am not a huge fan of Arizer just because I prefer convection vaporizing rather than conduction, and Arizer vapes are mostly conduction. I prefer a faster extraction and shorter sessions. Sessions with an Arizer can go on for 15-20 minutes depending on the temp, it's definitely a real session style vape. If you vape high temp starting off it might extract faster and be a shorter sesh but still a risk for combustion. Also with conduction the herb is being heated when not being hitting the vape. If you let it sit too long you roast the bowl. .... The Arizer Extreme Q tabletop vape is convection and a beast however so that's one to consider. You can also fill bags and take huge rips like with a Volcano. They are a great company with very high quality vapes but like I said it's really dependent on how much you want to spend, your smoking style and frequency of use, portability, etc..
