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?

Not quite.
What I was trying to say is that every electric heater will produce the same net amount of heat for a given amount of power consumption. An oil-filled 800W heater will produce as much heat as an 800W ceramic heater in 1 hour of operation, and will cost the same amount to run. If one has a fan, and the other does not, the one with the fan might distribute the heat more evenly, but their operational cost and net output will be the same (within a very small margin that is insignificant).
