Is it the arithmetic mean or weighted mean that is more accurate Why?
The arithmetic mean and the weighted mean are used in different situations. The arithmetic mean is used in frequencies as a general average.

It is not a matter of accuracy it involves using the right mean in the right situation. Almost always (if not always) a question will specify which mean to use.
