Unique_ptr offers many advantages: 1) Exception safety: what if you throw between your new and delete? Unique_ptr will clean up for you anyway and leave you in a stable state. 2) What if you forget to delete or your delete code never runs? Any of the many problems associated with explicitly writing delete can be non-issues with unique_ptr. 3) Clarity. When you see regular pointers in C or C++, it is never immediately clear who owns them. With unique_ptr, you don't have this problem because it doesn't look like a pointer. If you therefore see pointers, you know immediately they are non-owning. 4) Convenience functions like reset() on unique_ptr handle the release of the old and allocation of the new simultaneously. In general, the less code you have to write is often the better path to safety and maintainability. 5) Unique_ptr handle resources other than memory. It can be used to handle file streams, DB connections, etc and automatically close those also, if you provide a custom deleter function (which can just be a lambda, for elegance). 6) Unique_ptr is not copyable. This is important: if you own resources, it force you to consider this when you copy objects, and the compiler will force you to write your own copy constructor. Without this, it is easy to get into trouble if you forget these things with raw pointers. 7) Many syntactic improvements: i.e. unique_ptr will automatically call delete or delete[] based on what needs to happen, you can't accidentally get it wrong. This is just a start list. The value of unique_ptr is considerable.
