Different strokes for different folks, we love our glass top stove, had gas , had coils in past, can't see going back to that. Love the easy cleanup if something jumps from the pan or boils over. There are circles on mine, 2 small, one medium, one large. I center the pan on the circle using a similar sized pan as the circle. Our next stove will be bought with bigger circles ( burners) so we can have 2 large skillets going at same time.
