Mac OS. Any of them, they basically get better each time. Used it since MacOS 7, up to two or three versions ago because my laptop is too old to upgrade. Always liked it way better than Windows, it's just easier to use. It always feels like everything is always hidden somewhere or has to be done in some strange roundabout way. Regarding Windows, 7's the best one, better than 10, definitely better than 8. XP and 98 were also good, 95 was decent. Have no real memory of 3.1. Vista and ME were absolutely terrible in every way. Before those, I never knew a particular shade of blue was actually a color.
