I use both F and C (I grew up exclusively using F, but now I have a lot of experience with both), and I prefer C. It's more handy for cold weather because freezing is 0° (which is way less awkward than 32°), and it's more handy for cooking because boiling is 100° (which is way less awkward than 212°). It's also nice that the human body temperature is a round 37° (rather than 98.6°). For warmer weather, F and C are about the same to me. It's easy to remember that 20°C is perfect, 30°C is hot, and 40°C is miserable — just as it is easy to remember the equivalent 70°F, 85°F, and 100°F. So I have found that C is better for day-to-day use, even though it's not what I grew up with and I have drastically less experience with it. All I needed was a little time to get used to it.
