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. :)
