Cast iron Griswold #11 for steaks, burgers, etc., absolutely. There is a skill to searing and cooking, but once you get it down, you may never want to use a grill again, as the flavor is incredible. I gave away my grill several years ago. Cast iron cooking has replaced most other methods.
To each our own. What floats my boat may not float yours, but you may want to try..... Some people like cast iron, some do not. I converted at about age 50 and wish I would have decades ago.
That's a #14 Griswold skillet that I use for browning my meat, onions and peppers together at chili cookoffs. It will hold 3 pounds of meat, 3 onions and 3 peppers. Browning everything up sort of puts on a show for the spectators.
