Congrats on kicking tobacco. I have an assortment of vaporizers as well. I don't have the ones you have, but I have the S&B Plenty, which is a handheld-but-not-portable vaporizer that sort of looks like an electric stapler with a tube sticking out of it. It's powerful and useful, though. But we also got the S&B Volcano recently, and that sort of makes the Plenty less useful. I like being able to create custom vapor flows with the Volcano and an app on my phone. I find myself just smoking more often than vaping, though, despite having all of those fancy tools.
