For me, remembering numbers; like ID numbers, part numbers, phone numbers, etc. When I worked as a parts guy at a shop, I would frequently be able to bring up the exact part that fits the customer’s machine assuming I had looked it up once or twice before. If it was something I hadn’t looked at in a while I’d still usually double check fitment, but I probably had a 99% accuracy on part numbers.
Windows 10 on my main (gaming) PC (honestly I would probably upgrade to 11 by now if I didn’t need to do a BIOS update), and Ubuntu on my computer in the living room. I would try a different distro, but honestly whenever I need a guide to do something on Linux they’re always written with Ubuntu and it’s default commands and packages in mind so it’s just easier to work with
