Oh yeah I absolutely recognize that what you're used to or brought up on is gonna have a huge impact on which system you prefer. That being said, I think a Fahrenheit user would have a harder time switching to Celsius, than a Celsius user would switching to Fahrenheit, at least for normal day-to-day weather applications. And for some of the same reasons that people prefer metric units in general - it's more granular, has more resolution, is base 10 (for this application), etc.
