I think destructors are different, not better. A destructor can’t automatically handle the case where something doesn’t need to be cleaned up on an early return until something else occurs. Also, destructors are a lot of boilerplate for a one-off cleanup.

It can. An object with destructor doing clean-up should be created only after such clean-up is needed. In case of a file, for example, a file object should be created at file opening, so that it can close the file in its destructor.

That’s fine when one wants to write a whole class for something. But sometimes a cleanup path is genuinely a one-off, and using something like defer is nice.
