Okay so fahrenheit has a well-defined high and low, but an arbitrary freezing point of one certain chemical. All other chemical freezing points are arbitrary.
Celsius has an arbitrary high and low, but a well-defined freezing point of that same chemical. All other freezing points are arbitrary.
If your motivation is to minimize the amount of arbitrary values you have to memorize, fahrenheit is the clear winner.

Is it? Only pure water will actually freeze at 0c. Rain, puddles, lakes, etc aren’t all that pure… And we’re talking about ambient air temps here. The air can be below freezing and it can still rain. And you can get snow/hail above freezing…
Knowing the freezing point is just one factor. Knowing it’s generally around 30F is pretty much always close enough (not that remembering 32 is actually very difficult)
