That hasn't been my experience. TM2 makes me cough my lungs up at low temps. High temp vapour can be quite smooth depending on the device. High temps on the ZX go down smooth as anything. Don't think I've ever coughed once using it.

Simple is the way
Same here, I find higher temps with denser extraction to be smoother overall. IME the terps at lower temps can be irritating, and low temps require more draws of hot air to extract fully. I read a story here on FC many moons ago where someone was using a volcano to help medicate their aging grandmother. For her to be able to enjoy the bag without coughing fits, he would first run a low-temperature cycle to kill the terps enjoy that himself then run another bag at max temp for granny's meds.
Great story about the Volcano. The more terps I get in my sessions, the more likely I am to have a cough the next day also.
I can put half a gram through my ZX with high temp one hit bowls, and the next day my lungs feel great. But a TM2 or the coiled Quartz caps can really irritate my lungs. It's definitely the terps.
As long as the hit is adequately cooled, high temps are smoother imo.

I find certain genetics/ flavor profiles (terpenes, flavonoids, esters, phenolics, etc.) cause more irritation than others and noticed the “ideal” vaporization temperature vary from strain to strain.
I think the irritation is caused not only by a certain temperature threshold but the combination of the temperature and time. The residence time the vapor is in contact with your mouth, throat, lung (one hit high temp extraction followed by room temperature inhales vs 5 hits at medium heat over the same time causing more irritation to some).
With the Tinymight back-to-back bowls with the same stem causes the stem to get too hot, diminishes the cooling balls effectiveness to the point the stem is sometimes uncomfortable around the lips.
Swapping the stem out with another room temp glass stem, I heat soak the herb chamber/base of stem without inhaling to keep the rest of the glass stem and balls cool and follow up with a quick extraction allowing the balls to cool the vapor path more effectively for a smooth flavorful hit.
Your experience is contrary to mine. I much prefer low temperatures because that's where you get the best flavour, and for me the least irritation. Your tolerance for terpenes and mine are clearly quite different. As for particulates, that's just basic science. Why do you think higher temperature vapour is cloudier?
Edited to add: I'm not trying to tell you how to vape. If you've found something that works for you, great. Stick with it. For the reason I've stated, I don't think it will work for a lot of people.

I also find it higher temperatures are cloud here. 160 to 175 Celsius generally results in pretty wispy vapour for me. Tasty. Tasty, but wispy up around 200°C you got a lot more visible vapor.
Oh I don't doubt you on particulates. I'm just saying for me terps are a bigger factor for irritation for me.

I was also finding that the later hits on my TM2 were harsh and something that correlated with higher temps…but then I added a finer mesh screen and worked in some ball cooling and harshness is all gone. I was mobilizing but of tricombs in the pure convection wind stream…could even see them. Now with the screen in place and extra cooling I go from tasty terp-rich hits to mild nutty flavor to no vapor at all with none of the harshness. So…if you are chasing terms with a convection style vape and it’s harsh…I’d take a close look at particle mobilization.

Because there’s more vapor being extracted? Honestly, “particulates” is a vague enough term that it’s not really worth getting into a debate about (fwiw, you can count me among those finding high temp vape hits to be less irritating than low).
Vapour is colourless. It needs something to condense on, which would be the particulates released by heating. You can't see it until it condenses.

In a vacuum, sure. Your typical home atmosphere has more than enough particulate floating around for vapor to immediately condense, regardless of particulate being released from the flower.

Can't vapour condense on itself? Like in the case of water vapour, the particles collide and that's what creates a white mist?

I think you're right. Same for clouds.
That is not how it works. Clouds form when the air is saturated and cannot hold more liquid, so it condenses into water droplets.

I just meant that the plume of white you see is due to lots of these micro droplets together making it appear as mist/steam/vapour. Furthermore, do you actually really need "particulate" to condense on? Can you not get more vapour with higher temp due to more vapour condensing because of the ambient air temp difference?
Yes, you do need a substrate to condense on. You do get more vapour with higher temperatures.

Correct… but the air in your house (unless you’re living in a hyperbaric chamber) is already loaded with particulate. The substrate is present, regardless of the temp you’re vaping at.
That's an interesting point; however, it does not conteract the fact that increasing temperature also increases the quantity (and size) of particulate matter released.
