if u mean cooking range then gas one is better, but u can buy as ghazala suggested a combined one which generally comes with 4 gas heads and 2 or 1 electric head.
if u mean only the oven stove then the electric one is better coz for cooking/baking things we need to turn on the down part only then turn on the top part only and that will be difficult with the gas stove as it is difficult to turn it on.
