From my view, cannabis consumption is such a personal thing, both in effect and also preference. So many ways of taking it alone it's a pretty boggling choice. And that's just a small part of the equation.
I don't think it's possible to get a huge amount of help from others beyond giving options that may be unknown previously. Knowledge of course is power, if you choose to use it, recommendations can open doors to researching, but have to be taken carefully due to personal differences. I found in the end, personal experience was the bottom line for all these devices. One person's annoyance at setting up a device can be another's much treasured ritual. And so on. If you have anyone whom you can ask to try their vapes that helps. (Maybe that's one source of VAS?)
Most vapes seem to fall into a number of categories, and these categories have various pluses and minuses, depending on your own preferences and requirements. You can build those categories yourself according to what matters most to you - taste, effect, cost, speed, convection/conduction, whatever affects the aspects your interested in.
Maybe thinking on why you want another one, may help to focus on the parts that matter most (portability, ease of use, etc etc). What is the dynavap not giving you now? If it's strength, for instance, remember increasing tolerance will make the next stronger vape gradually reach the same point - is the new one able to adjust bowl size? (just for example), can it take a spare battery (if you want longer sessions later one)? And so on.
But in the end, I'd recommend trying a cheap but popular (in these hallowed annals) vape, one of the type that seems to tick most of your boxes.
But treat this as a research project, you may well not find it ideal, even though the type is what you're after. That first one will teach you what you personally care about most, show you where it fails your needs, and educate you in homing in on what will be your 'perfect' vape (as if there was such a thing!
).
There are some very decent but inexpensive vapes around, the popular one's will be more likely to be better, but more than that, will have suited more peoples needs, hence more likely to suit yours (statistically speaking at least) but better, there'll be loads of people of all sorts in the forums to help and advise on it, and info to read through before buying (what goes wrong, how good is after sales, spare parts, add-ons, etc). I strongly recommend against going top-end straightaway, unless your wallet/purse/pocket can afford to waste the money, as even a good vape of the wrong type will disappoint.
Finally, if you care, are you aware of your biases? Are you happy to let the form take preference over function? Have you considered the whole topic of making rational choices when you're an irrational human being? (as we all are by nature).
I'd suggest if you really want to be precise and accurate in your choice, get some paper and pen, and start writing down the things that matter to you regards the putative new vape.
Then you should be able to build a pro/con list of the good and bad things about the vape. Then, when you make a choice, you can ask yourself how well it actually fits that list, or how much you've been influenced by subconscious stimuli? (which is fine, but much better to know yourself, you'll likely make better decisions in general, but it's not as much fun as just letting your biases and prejudices choose for you!
).
