Great question! A kitchen remodel is always so daunting especially when you are trying to pick out the right equipment. I have cooking on most of all these products and it looks like you are looking for a feature rich appliance that will allow you to produce all kinds of culinary creations.
With me it comes down to Wolf and Thermador because both are fantastic quality products that really rock in the kitchen. I like the 8 burner Wolf, but I think there is a little better options out there especially for someone who cooks.
Look into the Thermador Pro Grand Steam Range: Link attached http://www.thermador.com/cooking/ranges/prd48jdsgu-48-inch-professional-series-pro-grand-commercial-depth-dual-fuel-steam-range
This thing is a hoss and destroys anything that is on the market. First of all you were talking about burners. This has 6, 18,000 BTU burners and one that is 22,000 BTU, which is rockingly hot. You can effectively use this as a wok burner for a small wok. It also has a griddle that is thermostat controlled. I love that because you not only get a griddle, which is consistent and even but you can use it like a kinda sorta french top. Turn it down to 200 and hold sauce or soups, or crank it up to cook on. You gain functionality without loosing two burners. It also has a grill attachment that is great for quick things like burgers, fish, shrimp, etc... Also, 4 burners have extra low, which will soon to be one of your favorite functions of the stove top. I can melt chocolate right on the stove top without burning it.
Onto the ovens. One of them is just a regular convection oven, pretty standard. The other one is a combi steam oven, which is awesome! you can do all steam, all convection, or steam convection. You will get better product out of this oven and it will be like transporting a little restaurant into your kitchen. It will soon to be your most used piece of equipment in the kitchen. I won't go into all of its features, but just know you will get a better product for most all things. Once again, you gain functionality, but do not loose a convection oven.
It also has a warming drawer built into the range, which is nice.
Finally, they are running a promotion that if you buy the range you get a free dishwasher, and a rockin dishwasher at that. If you buy refrigeration too, you get the hood and blower free. Awesome deal! http://www.thermador.com/about/promotions
