We did a lot of soul-searching on oven+cooktop vs range in our
kitchen addition project. The high-end ranges (Thermador, Wolf, Viking, Kitchen-Aid, etc.) have a few downsides:
1) Cost
2) Reliability -- Consumer Reports is not fond of them, GE, for instance, is much more reliable
3) Ease of cleaning (although the latest Thermador burners are a little nicer than the ones I got 18 months ago)
4) Even the widest versions have limited double ovens
5) Cost
We settled on a gas Thermador 6 burner+griddle cooktop (48" wide), and a GE double electric oven. MrsF was reluctant to get an electric oven, having grown up on gas, but has fallen in love with the convec and proofing features, and it's been a great performer. On wall ovens, there are very, very few gas versions, and we did not see any doubles at all. All in all, the double oven plus the 48" cooktop came to a little more than half the equivalent range cost.
