Think these really suited tradespeople that use same stuff all the time. Keep it all there, ready to access, not mixed up in the truck in buckets and such.
I rarely did the same thing repetitively, and mostly did very remote, difficult or long access jobs. I would think through the job ahead of time, mock it up in the shop if I could, and then pack specifically for that job. Mostly in milk crates, sometimes bucket organizer with stackable tray for fasteners, and 5 gallon buckets of sorted categories of tools for particular parts of the job. Cardboard boxes packed with materials for the job, sorted by phases.
Only constant was my electrician tool belt with about a dozen things in it, and a standard toolbox with comprehensive sae and metric 1/4" socket set, metric and SAE ratcheting wrenches, adjustables, hammer, hex keys, pliers, drill and impact and boxes of bits for each, tape measure, speed square, pencils and sharpies, 120 piece ratcheting screwdriver set, a hack saw and two pipe wrenches.
I tried bucket boss, tool bags, plastic boxes. None worked particularly well and no real improvement over just using a 5 gallon bucket or a milk crate.
However, I really see the value of having everything there and organized for people that do a repetitive trade.
