I find that increments of 1C are too small to be useful in daily life but increments of 5C are quite big. As a result, you can't really round degrees Celsius to a multiple of 5 whereas full precision integer temperatures are too precise. So for example 15C and 17C feel like different temperatures, but each 1C step from 15C to 16C to 17C is not really useful.

In contrast, it's very reasonable to round temperature to increments of 5 degrees Fahrenheit. So for example 58F and 60F are basically the same temperature as far as my perception is concerned.

It's literally does not matter in day to day life. In the end you get to X degrees is cold, Y degrees is perfect and Z degrees is hot regardless of C or F.

I grew up using C and now I'm using F, if I move to a country that uses C, I will switch again. Its meaningless.

This is the correct take. The better system is the one that you have intuition in - just keep using that one if building up intuition in a different system is not worth the cost to you. At least when it comes to temperature. :)

What are you talking about? The same can be said about 59F (15°C) and 60F (15.56°C)

"One fahrenheit increment doesn't feel like anything"

At least Celsius are grounded in reality, should I be worried about ice? Just check if temperature is below 0°C. But hey you may need to check if your solution of water, ice and ammonium chloride is frozen, so I just need to check if below 0F. That's probably something you do often right?

theyre both grounded in reality because the represent real temperature conditions.

theyre both just arbitrary degrees though, since 0 isnt actually 0. they both have better alternatives too - Kelvin and Rankin. your criticism about freezing applies to celsius too. freezing is at a certain pressure and temperature, so both the 100 and 0 celsius only sometimes describe boiling and freezing

I can sense 0.5C changes when I set my AC at home.
