In what sense? Both have BTU ratings to determine their capacity. Just for kicks, I looked at a few units online at a mid-range price point of about $1500. The gas ones had 18-20 kBTU burners and the electric were around 10 kBTU burners, so the gas has considerably higher output. As you say, gas is basically instantaneous once the flame is present while electric has a lag, so it's going to take longer to get to that capacity for the electric. Maybe your point is that electric transfers heat better? I couldn't find any sources on that. Add to it that the colors of the flame/heating element as a general rule of thumb for temperature, the gas is higher on the temperature spectrum.
