I just ordered the original DaVinci (2nd revision) for my first vape. For a possible upper-end secondary unit, I've narrowed it down to the Arizer Solo (newest model), the Pinnacle Pro, and the new DaVinci Ascent. I mostly care about the overall vaping quality, and efficiency (to get the most out of my herbs). Excluding the portability factors of these units, which one wins in the ring!? Thanks!
