You will have a memory leak.

In that order, no, because it is not exception safe. If the allocation or object creation fails, you cannot restore the object that you just deleted.
Whether the approach of creating a new object and deleting the old one is better than reusing the same object depends on the use case. You didn't provide enough details to say anything specific.
