Safer for what? That opinion seems to be misguided to me.

strndup prevents you from overrunning the allocation of a string given that you pass it the containing allocations size correctly. But if you got passed something that is not a string, there will be a buffer overrun right there in the first line. Also what outer allocation?

You use strcpy when you get a string and memcpy when you get an array of char. strncpy is for when you get something that is maybe a string, but also a limited array. There ARE use cases for it, but it isn't for safety.
