Correct. Converting electricity to heat is pretty straight forward, it involves a big resistor at the core of it. You can do various things to move the heat (fan), or create things to help store and radiate the heat more slowly (oil-filled), but at the end of the day, the power usage, operational cost, and total amount of heat created will be the same for any given wattage.
Also, all electric heaters will be equally efficient, a 100W heater costs 1/10th as much to run as a 1000W heater, and it will heat the area 10 times slower. But they will both use the same amount of electricity in the end to raise the room temp by 3 degrees, for example.
