It is highly useful when salting meat, or any large piece of food because you can see how much salt you are applying, unlike table salt, which dissolves almost immediately.

In my opinion seasoning meat is just short term curing, i.e. I do recommend flakey salt for that. It's useful less for being able to see the seasoning but the larger grains draw out more moisture/season deeper.
