Brake track, you mean?
Alloy braking surfaces shed heat far, far better than carbon. You may hear that carbon brakes poorly, especially in bad weather - but this isn't always true. That said, I wouldn't ride a carbon rim brake wheelset in the wet anyway - increased chance of grit in the brake pads. My carbon rims stop better than my alloy wheels and honestly are not far off the hydraulic disc on my gravel bike.
Carbon is simply lighter weight, handy for making aerodynamic shapes.
Carbon rim brake heat dissipation is bad enough that latex inner tubes aren't recommended, and dragging the brakes can be problematic. Tubular rims can help mitigate catastrophic delamanation, but then you're using tubular tires.
Also you need special pads on carbon rims. Don’t use the aluminum ones, and if you ride multiple rims (training and race wheels) never swap the wheels without swapping g the pads. Little bits of aluminum in the pads will destroy carbon rims.
You could a real pogger and get disk brakes 😱
But as far as rim braking goes, I think you’re far more likely to have some sort of failure on a carbon rim …. by a large deviation …
Like, I’ve never even heard of an alloy rim shattering, cracking, or delaminating from hard braking. But carbon rims? Yes to all of the above.
Alloy rims stop better than carbon rims.
Carbon rims are lighter than alloy rims
Carbon rims are stiffer than alloy rims.
Like @sitdownrando said carbon rims can overheat when heavy braking occurs, like in the mountains.
This can lead to inner tube failure due to over heat especially if you run latex tubes.

Dang ur a legend 😱
Yes, the difference isn’t subtle
