I keep seeing people say this as a benefit of glass-top electrics, but this has never been the case with any one of those I've used. A boil-over invariably leaves a grimy black ring that can't be scrubbed off even with hours of scrubbing. So they end up looking grimy.
Meanwhile, my sealed gas burners are easy to get clean. I just sweep up the crumbs and then dump some boiling water and a couple drops of dish soap and wipe it up.
