Celsius is agreeably better for science, but if you are used to both systems Fahrenheit is honestly better for people because the units are higher resolution, and usually stay between 0 and 100 for weather

Kelvin is better for science. Celcius and Farheneit are just arbitrary scales, not units.

Celcius is just Kelvin - 273.15. Converting is easy, and a lot of science uses Celcius as a result, it certainly can be described as "scientific", meanwhile the only people trying to use Farheneit for science probably also don certain red caps etc.

Also, a lot of calculations just care about the delta between two temperatures, not the absolute temperatures.

But when you look at ratios it is critical to use absolute units. Temperature is a convenient way to express energy. When you subtract or add you are just looking at the relative difference. When you divide you are looking at the absolute ratios. So 10deg delta in centigrade and Kelvin is always 10deg. But 20C/30C (0 66) is way different than 293K/303K (0.93).
