Portable USB-C soldering iron GD300

Reviewed GVDA GD300, being designed the modern way, is powered by USB-C with PD 20V 65W and QC support, and fortunately also by custom power supply within voltage range. T65 system of directly heated tips, being fully compatible with SH72 derives from legendary Hakko T12, while also being compatible with the legacy T12 (but not fully). Why are the directly heated tips the top of the line, and how so, that such a 65W soldering pen can easily outperform big chunky branded overpriced soldering stations from renowned brands, even if they have slightly greater power? This, and even more, incl. my personal experience and footage of soldering under microscope (Andonstar AD207) is the subject of this video.
