I couldn't figure the difference between these two ranges, so I asked Neil.
Neil and I actually grew up together in Needham, and he has been at Yale for 20 plus years, so he knows the difference. Lets look at these two very popular slide-ins, the GE Profile vs the Frigidaire Gallery.
They both have convection (fan forced heat for even cooking), a bridge element (connecting two burners for continuous heat) and a fifth warming element (guess).
The GE has stainless knobs and a triple burner (varying heat control for different types of pots), so ostensibly it is a better range.
However, the GE Profile costs $2059.....the Frigidaire...$1299.
