Newer technology doesn't mean "better" in all cases. I hate comparing apples to oranges, cars vs mods. But since it was brought up before...
Old school audiophiles swear by the old tube style amplifiers compared to modern day's solid state digital media. LP discs over digital discs for higher fidelity. They argue that a sense of "warmth", "smoothness" & "realism" is missing in digital media. To these people, newer technology is not always better. These arguments are all in the "ear" of the beholder. I get that. Not everyone does, though.
In vaping, the debates persist in the differences in the PWM/VRMS frequency of regulated devices. The "rattlesnake effect". That 33.3 Hz devices vape harsher/hotter, and higher 800 Hz devices have a smoother vape. I experience it with my regulated mods. I swear my Provari's vape smoother than my Smoktechs, Segelei's, and Innokins. It's in the "vape" of the beholder. I get that. Not everyone does.

If you want to get technical with vapor output accuracy with PWM, VRMS values, PBusardo explains it here in this video:
