I think it depends on your climate. Geothermal is better for colder climates and air-source pumps are sufficient in warmer climates.

I think geothermal heat pumps are more efficient, but they are also more expensive. They also face more difficult permitting restrictions, if allowed at all, and require the ability to disturb a decent sized area of land.

I agree with the other commentators. Multiple factors such as climate and the specific heat pump design (manufacturer/model) determine which type of heat pump design is more efficient. In general, geothermal heat pumps are more efficient since they utilize the temperature of the ground/water which is more stable than the outdoor air utilized by air source heat pumps. Also, there is a significant difference in efficiency among heat pumps even within the air source heat pump designs depending on manufacturer type. Eg., Mitsubishi and Fujitsu are almost twice as efficient as other air source heat pump brands.
I don’t think efficiency should be the only factor consider related to heat pumps. There are so many other factors also to consider related to heat pumps. Eg., just a few of the factors are whether you’ll be generating your own energy to power the heat pump, type of climate, available installation space, heating and cooling needs, available land for the installation, manufacturer warranties, maintenance, installation costs, regulations and incentives, and property design. I always recommend for people to have a total retrofit/design plan for their property, including transportation, so they can go 100% “net carbon zero” and save money while doing it. For example, if you have your own solar system, then the energy to power your heat pump won’t need to be purchase from the utility, but you’ll want the most efficient heat pump out there since it impacts how many solar panels you’ll need.
