We're taught both metric and US customary units in school. I prefer metric for most things, to the point I have a metric-only tape measure among other things.
However, I'll die on the hill that Fahrenheit is superior for ambient air temperature. 0 degrees to 100 degrees neatly encompasses the range of average surface temperatures seen throughout the year in the contiguous US.
Prefer metric. So much easier conversions. However, it is hard for me to think long distances and weight in terms of metric, on the fly, and ambient temperature.
Also a lot of tools are still in "standard" so have no choice but to use it.
