I worked for a Mercury dealer for years, I've had a set of their carbon hoops I laced to some Hopes, currently have a set of carbon wheels for my gravel bike, and have ridden a few aluminum wheels. The answer to all the questions, is, they are fine. I would not hesitate to ride any of the carbon disc wheels on the road unless you're really picky about the hubs. In general the hubs are mediocre, but what do you expect for the price? I would personally steer clear of the aluminum mtb wheels, especially if you weigh more than 150 or ride aggressively.
