I used to use NDD because it was more verbose, and seemed more reliable (unlikely to crash itself, at least), but lesser performance and consistent issues with localized filenames prompted a return to good old scandisk.

Overall, NDD isn't so great. It has a plethora of issues, and doesn't apply fixes smoothly enough.

At any rate, with my current disk size, I prefer only to run a scan when there is valid suspicion of a file-system error, and do so manually. After all, it can easily take the better part of an hour with modern disk sizes.

There's useful info findable by folowwing the links in this post. HTH
