I got a buddy that builds drag cars and his only heat is radiant. He said it is cheaper to run but more cost up front.
I didn't like it. My feet were sweating and still had to wear a sweatshirt/jacket in the winter.
If I was to build a shop and money was no object/concern, I would put it in but keep it set to like 50/55. Then have a propane/natural gas forced air. No tool sweat, no dampness, etc.
It comes down to if using it for a work space or storage space.
