Also, are you saying that all types of space heaters work equally well? E.g., oil-filled radiator vs infrared. Or are you just saying that two devices with the same amps or watts are going to cost the same to run, regardless of how well they heat?

With the same amps and wattage... they should cost the same to run.
The difference is the conversion of that electricity to BTUs.
Think of it like a light bulb... all bulbs produce light... but some produce more heat than others. Since the purpose - generally - is to produce light; the heat is electricity being wasted.
The fan doesn't produce heat, but it does consume electricity.
The radiant heater allows you to feel warmer because the infrared radiation is projected directly at you, rather than heating the air and blowing it at you. Because of that, you may find yourself running the radiant heater on a lower wattage... thus consuming less electricity to get the same feeling of warmth.
