Or, to be more precise, EXACTLY the same. 100% of the electricity you consume is turned to heat.
Pick whichever one you like best.
Those with thermal storage
(e.g.; oil-filled) hold the heat a little longer while the thermostat is off. They are also often designed to encourage convective air currents, instead of using a fan, which is nice if you want quiet. But a fan will get more air moving, so you'll have fewer cold spots.
There's absolutely no economic benefit to "ceramic" heaters. Again, even the $15 Wal-Mart specials (sometimes on sale
this time of year for $10) are 100% efficient.
At least in the US, it's the law that electric heaters have an automatic shutoff if they fall over. Usually it's a switch on the bottom. But that won't prevent you from accidentally leaving paper, blankets or towels too close and starting a fire. This is where the oil-filled or ceramic can help, since they may be cooler on the outside.
