Butter is absolutely fantastic! As long as it's a grass fed organic butter such as kerrygold. (http://kerrygoldusa.com/products/butter/). I tend to prefer the taste of frying something in butter over coconut oil simply because I do not care for the taste of coconut, which does come through if you are using unrefined coconut oil. However, if you enjoy the coconut taste I think either the coconut oil or the butter would be great. They are both healthy for you. You could try the different options with different meats and veggies to see if you prefer different flavor combinations.
Good luck and healthy eating!
I fry low-temp stuff in butter (eggs, asparagus, mushroom, etc...) but frying a steak or a stir-fry, you usually want to crank up the heat. This will basically burn the butter. Still tastes good but you've oxidized the PUFA's (killed your omega 3) and denatured lingering milk proteins. Ghee, tallow, and coconut oil are good for high-heat frying. Olive oil is somewhere in the middle.
