C++ When should we prefer to use a two chained static_cast over reinterpret_cast

Which is better?

static_cast<T *>(static_cast<void *>(buffer));

or

reinterpret_cast<T *>(buffer);

Where buffer is char * (memory chunk which contains values of type T).

Answer 1

The chain of two static_casts is better - it is less implementation dependent.
