Imperial, American Range, and the others...
They make heat. It's just like a domestic range where 99% of the time it is the person doing the cooking. Your food won't come out any better on a $5,000 range or a $300.
I have been a Chef for my entire life and can bake and cook well on my next to BOL 12 year old Kenmore Range.
The only range that I truly detest and just cannot get used to is the Glass Top Electrics. I only have the pleasure of a glass top is when I go to my Dad's house for a visit. I just find them truly painful to cook on them due to hard to control heat. The concealed element oven too is another favorite. ( Not )
As far as electrics go, Calrod, Corox, Radiant Tube, and Induction are fine with me. There is just something about those Glass tops I find tough to adjust to.
