We don’t have an outdoor kitchen, but do tons of cooking outside with the Coleman stove and an electric frying pan. We often camp with cousins that have the big fully equipped outdoor kitchen. The biggest benefit that I see is we camp in jasper and Banff and are required to keep everything bare in the campsite, anything related to cooking or food cleaned up. I spend time packing everything up between uses, and the cousins come out, slam shut the big door on their outdoor kitchen and they are good to go.
