As opposed to cast iron on a gas stove? Or as opposed to other pans?
Cast iron definitely is different for a variety of reasons simply given the way it conducts and retains heat in a more even distribution. I'd be surprised if you get that much difference from gas heat vs wood, though you did say "fire", not "wood" so I'm probably making assumptions anyway.
Perhaps the biggest issue with electric I have is being unable to actually turn DOWN the heat quickly enough. Even if you've stopped sustaining or adding more heat, the element continues applying heat to your pan. It's almost less of an issue with cast iron than stainless steel or nonstick because the cast iron is going to hold heat and apply it to your food regardless, but it does still make a difference.
At the end of the day the temperature of your heatsource is going to change the dynamics within the metal you're cooking on -- I'm now curious how hot my electric cooktop itself gets when compared with the flame of fire or a gas stove. Never mind the super-charged propane wok burners I've been drooling over.
