Right but efficiency doesn’t mean it’s better. Electric heat has always been 100% efficient, but that has not made it the most cost effective nor the best solution over far less efficient means of generating heat either. Efficiency isn’t the only factor. The debates and critisms here are valid from what I’ve seen.
Personally, I’m not sold on them… maybe if I lived someplace warmer but living in Wisconsin, they are not for me. I’ve also seen that they require a lot more maintenence and are much less resilient compared to furnaces and central air units. I’ve watched plenty of installation and repair videos on them. Even the HVAC guys have issues with them in these terms.
