Over the decades,I've installed them all. Even had three types in my house - electric baseboard, heat pump, and finally baseboard hot water. I use baseboard heat because it is the most efficient - that is - a 3/4 inch tube, even uninsulated will lose less heat from its surface than a duct that is so many square feet of surface to equal a poorly insulated room AND I don't have cold breezes while my warm surfaces send heat directly throurg the air from my walls to my skin.

My air conditioning is ductless as well for the same reason. I use a 1-ton unit to cool my home, where others have to use twice that due to ducts. Even with energy doubling cost in the past year, I will spend less than $2000 for gas and electric in the highest cost utility area.
Most of the American people are now getting in trouble from using up the energy in one hour today that people used for a month a century ago, riding a block to shop, commuting to school and work, watching people go around in circles or back and forth chasing a ball.
As a pro, I don't need to get a particular boiler, in fact, I can make one. The burners I have now I made 5 years ago after the burner wore out after a quarter-century. I have gas available which means I can make a condensing boiler near 100% efficient without needing a chimney, an exhaust fan, nor electric source while sitting outdoors.
This means that others with no skills in HVAC will have to buy whatever boiler the local plumbers ask the suppliers to carry, or else have to find someone remotely to supply and fix whenever there is a problem.
