Warning: I mocked chalk lines as overkill, but they saved my long cuts from drifting
After it kept my fascia board cuts perfect, I won't mark long lines without one.

That 16-foot board waving from a bad chalk line is a special kind of heartbreak. I've seen guys spend more time cleaning blue dust off the plywood than they saved with the snap. Sure, a speed square and a good eye works until your coffee kicks in and your hand isn't so steady. At this point, the argument is just guys picking their favorite kind of error.

Chalk lines suck when the wind picks up, dakotal49.

Respect the technique but find it adds more steps than it saves. A sharp pencil and a steady hand on a long level gives the same result without the chalk dust everywhere. That blue chalk gets on everything, stains the wood, and needs cleaning up before you can even think of painting. For fascia or any visible finish work, I want a crisp pencil line I can see exactly, not a blurry chalk mark that can shift. The snap line itself can wander if the reel is cheap or the tension is off, adding another chance for error. After years on a crew, we cut long lines fast and true with just a speed square and a practiced eye, no extra tools needed.

Totally get what you mean about the chalk line being blurry and shifting. My buddy learned that the hard way last summer. He was putting up fascia boards and used a cheap snap line he had lying around. The chalk was way too thick and the line snapped crooked without him noticing. He cut and hung a whole 16-foot section before seeing the wave in it. Had to pull all the boards and start over, wasted a whole afternoon. Now he just uses a long level and a pencil like you said, never looks back.
