What do you mean by stainless steel? Stainless steel pans are usually clad (3 or more layers with aluminum in the middle for heat transfer), and IMO wonderful to cook on no matter what generates the heat.

If you're talking about pure stainless pans, I've never seen one. I've seen pure stainless steel stock pots (though even then, most have a clad base). The thing about stock pots is that they're full of liquid, which convects and makes thermal conductivity of the hardware pretty much irrelevant. Never buy expensive stock pots.
