Not exactly why the cast iron makes more smoke and not sure I've adequately tested that, but think that's right. There's no way I'll heat a coated pan that hot no matter what the manufacturer says.
Iron is virtually indestructible and won't come off in your food unless you cook acidic items (e.g. tomatoes).

I would be more comfortable with a coated electric panini grill where the manufacturer has designed it for specific use with built in heating. OTOH you could heat a pan to almost any temperature you want, certainly several hundred degrees F, far hotter than would be safe to heat a coated pan. I'm not sure that would be a good idea for cast iron either but at least you know it won't give off toxic chemicals.
Iron is actually a necessary part of our diet. :)
