I also tend to be skeptical when I see something hyped, but I work in this space and I can say that this tech is really the best option for most residential applications.
It's old tech, it's been around since the 1800s. The only thing that has changed is that heat pumps have gotten cheap and energy has gotten expensive.
There are applications where heat pumps cannot replace boilers - in industrial processes where high temperatures are required or tremendous capacity is needed intermittently.
However, unless your temperatures are routinely below about -20 F, a heat pump is the best choice (and even if temperatures occasionally drop below that, heat pumps are still an excellent choice because those extreme temperatures might only last for a handful of hours out of the year, during which insulation or a cheap electrical resistance heater can keep you warm).
