You are essentially right, although all of these will require a warmup heat soak of ~10-30 mins. You need to get the housing and then the balls up to temp first, and then they usually hold the heat well, even with back-to-back hits. You will have no problem getting quick, dense hits with any of them. I think I would look at price and materials first as the hits will be there whichever you go with. Other things like compatability will matter as well (this is mostly in terms of whether your coil/pid pinout is universal or proprietary, or whether you go for an injector or diffuser head, etc.)
Regarding the PID, I don't think that I can choose there because I'll need the 230V EU plug version.
I think I will go with a Taroma with short 18mm glass bowl and the 220V PID.
But I'm not sure if I should get the OG or the 2.0.
Is the titanium bowl a must buy? I hope not because it's pretty pricey.
I meant with heat soak, that I have to place the Herborizer injector on the filled bowl for 1-2 minutes for instant dense vapor. On the taroma vape video they can place the injector on the bowl, hit and get immediately dense vapor. That's impossible with the Herborizer.Whatever you get, I would consider getting a common pinout so you are not limited in the gear you can use together. For instance, if you went with something large, you may also want to be sure there is also a variety of coils supported for your PID, in case you do want to add something more sipper-sized. There are some very high quality heads built with 14mm injectors, for instance, that can more easily handle individual dose sizes both because of the size and because of the tuning. They will still deliver the thick, dense, vapor, sometimes even much tastier as well if the head is well-tuned for lower temperatures.
