“Intuitive” is a meaningless metric for a single scaled number. Whichever system you are used to will be the more “intuitive”.

Also, climate can play into which system feels more useful. Where I live, 100F occurs only rarely (and since air conditioning is almost ubiquitous, not something I’d bother looking out for), while 0C is an outdoor temperature that I do need to be aware of for half the year.
