I prefer tea (and will only drink coffee if the 'tea' offered is undrinkable). The advantage behind drinking a hot drink during hot weather is that it raises your core temperature, so you have a lower temperature imbalance against the ambient temperature. Drinking a cold drink lowers your core temperature, increasing the imbalance, and causes you to sweat more.
When I drink tea it is in the way I prefer. For example, I LIKE Earl Grey tea with milk and sugar. When somebody says "That is not how you should drink Earl Grey tea" I respond that "That is how I prefer it, and as I am drinking it (and not you) I will drink it as I prefer it!!!"
I have found that if I have a sore throat Peppermint Tea helps to soothe it (if my throat is really rough a teaspoon of cough syrup in the tea helps even more; don't knock it until you try it under those circumstances!).
