Do you have a strict budget ?
What's your cooking style, mostly stove top, grill, griddle, oven use, rotisserie use?
Do u mind if appliances are different brands?

I don't cook much so the range mostly would be for the future re-sale value of the house. The designer recommended a 6 burners gas range. I don't mind if the appliances are different in brands. Every builders and designers we had come across recommended Sub-Zero refrigerator but customer reviews are not so great. I've been told Blue-Star range is good but can't seem to find reviews on them. My husband did not put a budget on the appliances. He just doesn't want to be the one calling for repairs. I guess what we are looking for is something reliable.

Lucky you, a husband with no budget control... several people around here are throwing vegetables at the screen in disgust (organic, locally-sourced of course) ;)

I would consult a local realtor or check our the high end spec homes in your area. I was told by an appliance distributor that Wolf was the marquee name that the builders were sourcing, almost without exception. They sold the rest as well. A BlueStar has foodie-appeal, but not quite the same marquee value around here. YMMV. If you go with the all-gas range, you might consider another electric wall oven, if you have space.

Judging from the advice I've read, the SubZero is your clear cut winner.

On the hood, you need to mention the style you are looking for.... are you looking for an insert or a full hood. And is it wall mount or island mount?

I agree with gooster, resale showpiece go with Wolf range. IMO it's best to visit showrooms, open and shut doors. Do you like the weight and feel of oven doors and racks. Are you ok with the way the grates sit on the stove top?
