I prefer them because the toughness of the chisel allows a much shallower angle grind to the cutting edges and this allows a more controlled carving action. I do own a number of carbide-tipped tools which I use when carving hard serpentines or granite.

Multi-purpose carbide drill bits drill through any combination of steel thickness, concrete, gypsum, and almost anything else, including granite, without the need for a liquid coolant. Hard as it may be, even carbide wears out over time and needs to be sharpened.
In fact, it is easier to regrind the carbide than it is to regrind the steel, because it can be done continuously without overheating. It is first ground with a fine silicon carbide wheel and then polished with a fine diamond grinding stone. Carbide is a bit like glass, as it tends to break more easily when scratched.
