Not really better, but certainly safer. Electric heaters are all 100%
efficient. Every watt you shove into the heating wires is turned into
heat. There's no way to improve on 100% efficiency.

It's certainly true that 100% of the electricity consumed by an electric blanket becomes heat.
No, that isn't true either. I write "either" because even _if_ it were true that electric heaters are 100% efficient (which isn't true), saying 100% of the electricity consumed by the device become heat is very different than saying it's 100% efficient.
I've always had a mindset for minimizing waste. For most of my life I was diligent about shutting off the light switch when leaving a room. But now I often don't bother, especially in winter. LEDs draw so much less electricity anyway, and in the winter the "waste" just amounts to electric heat.
