Our stove functionally has 2 ( front right and back left ) but back left is inconvenient if we ain't just putting something on to sit on its own. So we basically only have one in my eyes. So much more work to use it thanks to the oven controlls that I'll often switch to using front left despite it being too small for the pot/pan.

Take the small one and save energy (if not frying). It doesnt take much longer and the pot uses the energy more efficiently Edit: nm dont do that if the water is not yet boiling
