Front left. The left side burners are the same size. The right front is for soup and things that take a lot of heat because of the liquid. The right rear is a simmer burner that we pretty much only use for heating pasta sauce. If we still had toddlers at home, all cooking on the stovetop would be done on the back burners. It's gas, not electric. We had an electric stove and clothes dryer when we moved in here. The house was also configured for gas, so we disposed of the electric units and installed gas ones. They paid for themselves in ten months. That also freed up two 50A and two 30A circuits, as both the electric units were 220. One leg of the 50A I ran direct to the microwave oven. I broke out the two 30A circuits and ran them down the wall of the garage in conduit. They terminate in a 220 outlet and two 4-gang 110 outlets that are on different phases.
