they're all pretty much equal in terms of ratio-to-effect, from what I can tell. The wax is less messy as I mentioned. I scoop a tiny amount out (about the size of a pencil lead) into the chamber, which lasts for a very long time (days or even weeks, depending on frequency) About $50 of wax lasts me many months, based on a few hits every few days or so. Plus it burns down to nothing, when it's gone it's gone. No cleaning or scraping resin like in the old days with buds and a pipe/bong.
For me, the Dabber is very simple to use, and I'm not big on fussy or complicated technology. Once every couple of months I recharge it and refill the product.
I would definitely recommend some kind of vape pen if you'll be using it when you're sleepy. As another person mentioned, there are many types that are completely self-contained and disposable, for about $50-60 or so you can buy something that's ready to go anytime, at the press of a button, that never needs charging, and shouldn't clog on you. Anything cheaper than that, and you are likely to run into issues. For me the chemical thing is a deal-breaker, but my husband buys these every few months, and likes them just fine.
One final thought: Have you ever tried CBD tincture? If you're interested in relaxation/sleep, as opposed to altering your mood, that might be a good option for you. It's also helpful for pain relief. I put several drops in some water and within 30 minutes I just feel relaxed, less stressed, but not actually "high". The kind we got most recently has a combination of both THC and CBD (it's called "Mama Lou's CBD sleep tincture"; the label says 5MG THC and 30MG CBD. I took some a little while ago, and I feel a "little" mood elevation, but mostly just chill. The cost per dose in relation to effect seems to be about the same (maybe $40 for a 30ML bottle, which if taken every day would be around $1.30 per day). Just throwing another option out there for you to think about.
All the best!
