It’s really not that far off from the truth, this varies slightly depending on the utility (I’m on a notoriously more expensive one in my area). Very recent gas price increases have also pushed gas closer towards electricity but not by nearly enough.
That source is essentially lying to you. It's measuring electricity as "heat" by simply converting the energy value (i.e. as if you were using 1950's radiant baseboard heaters). Modern homes use heat pumps that are (literally!) 3x as efficient.
It gets away with this by admitting the error in the text ("The only caveat is that we talk only about traditional electric heaters. Heat pumps are another story."), but the numbers remain a lie.
In fact if you look at it, that site seems to me to be a for-pay blog. Most of the articles are just product "reviews", with the remaining stuff a mix of bland overview stuff and articles like this that seem to push an agenda counter to the presented theme of the blog.
Be careful out there. The internet is a wild place.
Sure, although it did somewhat align with my real world experience moving from a new house to another similarly sized new house. All else equal, I saw my total energy bill increase drastically with the heat pump, even with an 8kW solar system. Something didn’t add up, maybe it’s not working properly. It raised a lot of questions for me.
That said, it’s arguably really tough to compare these two heating systems objectively and you can’t take the advertised rating at face value necessarily. It’s not apples to apples. Electricity billing is complex and includes many more variables and gas is billed completely differently which adds to the comparison problem. Any comparison online ends up making many assumptions so of course we need to take that with a grain of salt.
