depending on your water quality(many radiant systems are in rural and suburban areas where people have lrger lots)
The water delivery piping can clog up with scale or be etched by low pH. The quality of water is more an issue with these than even with baseboard hot water.
Earliest forced hot air as passive with the large vents and returns along the wall sides.
We built an addition a number of years ago and investigated putting radiant heating. It was quite prohibitive because we needed a separate ZONE controller and all the stuff that entailed , separate pumps and tank swith a bleed system to periodically change the water so it doesn't get all pookey.
It would have been better to do the entire house biut that would have added another amount that, at the time , didn't make sense.
Ive since gone gas baseboard (from an oil system) an, since the price decreases of gas, Ive never enjoyed better economics in my system.
BAseboard radiators are less techy than radiant but now they have individual feedbacks with flow reducers and temp sensors for an individual room so that the system can deliver more or less circulated hot water and keep the rooms nce and equally comfy.
That's a retrofitters dream.
