My two cents
I despise electric cooktops, and since I entered rental hell almost 10 years ago, I have had nothing but electric cooktops.
I, too used to cook professionally, and electric cooktops, even when new and good drive me nuts!
The cooktop in the early 80s Tappan the landlord saw fit to provide is not good. Only one 8 inch element, and it has dead spots.
Also, I have a hard time stirfrying on an electric. It can be done, but I find it annoying.
To be most efficient on an electric, you have to match the pan to the element, and I hate that.
Electric ovens, however, are very nice, and when I finally escape rental hell, I am going to have a gas cooktop and at least two electric ovens.
But only SELF Cleaning! A manual clean electric oven is a bother and a half!
I grew up cooking on a Maytag gas stove, it was 40 inches, and when it finally died (after close to 38 years!) it was a challenge to go to a 30 incher.
I've seen that dual fuel one, and I like it. A lot.
No one manufacturer makes the best line. I hate to say that, but in my experience, that's the way things are. For example, I like GE cooking, but do not like GE laundry. I like Maytag laundry (at least my '97s,) but Maytag refrigerators don't seem to be as reliable as Whirlpool refrigerators.
The only reason I can see for buying a major appliance at Sears is if there isn't a good "mom and pop" appliance dealer nearby, or BestBuy.
Look for a Brand Source member store for an independent.
