It depends on my mood.
When i want the absolute best tasting steak I get a great marbled NYS and let it warm to almost room temp after seasoning it with some pepper, garlic, MSG, salt, pepper flakes, dill, and coriander. I then preheat my grill to as hot as it goes (weber ftw) and then toss them on for 2.5 - 3.5 min per side and then taking them off and letting them rest. This results in a medium rare- medium steak depending on thickness with great sear marks. Oh and make sure you put a thin pat of land o lakes butter on top if each of them before tossing them on, it makes them extra juicy and flavorful.
If im being lazy I have a set of cast iron pans that were my grandmothers that are solely used for steak. Same process as above but i make sure to blot the steak with a paper towel before hand to soak up any moisture, if you dont do this it steams underneath and ruins your chances of getting a great sear. With this method i keep the butter off until ive flipped it to keep the pan dry as possible so i get a sear on both sides. Spoon the butter/drippings on the steak for extra awesome.
