Seems to me that Festool’s entire product line is developed with folks who work in the trades in mind. I have my systainers loaded on festool hand trucks (which I find pretty crappy and flimsy, but they work) organized for installations on job sites. Super fast to throw in a truck or van and roll out and stay organized on site. I’ve worked around plenty of guys who poke fun at systainers and Festool, but also see how disorganized those guys usually are on job sites. In the shop I’m predominantly using larger stationary tools, but if I need a tool in a systainer I know exactly where it is. I also have tool cabinets and shop made drawers. They each serve a purpose. I don’t see it as one vs another or one is right and the other is wrong.
