The question really does need to be separated out by era. Are we talking Mac System 7 vs Windows 3.1, Mac OS 9 vs Windows 98, early OS X vs Windows XP, Intel Macs versus Windows 7, ARM Macs vs Windows 10, etc.? Each generation had a different user paradigm, and people who were good with one versus another might mean different things than other generations.
