I love the pro's/con's discussion of the "cluster" burners vs. the divided top. I've been wondering about the provenance of the cluster burners for years. GE's always had them; only when GE started outsourcing their 40-inch stoves to WCI did the divided tops appear. Hotpoints offered a few divided top 40-inchers along the way. From a little bit of research, it seems like the cluster burners were direct descendants of the wood stoves of by-gone days. As gas stoves replaced the wood/coal models, the layout persisted in the multi-oven models on stilts. When the first electric cookers were introduced they followed that layout exactly.
Also, most of those double-oven electric 40-inch stoves had a smaller, lower oven on the left side of the stove. So with all of the extra clearance, it was a good place to put all of that sensitive circuitry. I still think those 40-inch GM Frigidaire stoves were/are the best electric stoves ever made. Especially for people who actually cook.
