How do search engines view '-' vs '_' in URLs differently and which is the best practice for rewrites?

'-' is always seen as a space, '_' may not be. So '-' is the best option.

that is, an underscore is just another character, whereas a dash (or hyphen or minus sign) is a delimiting character. periods are sometimes used successfully also, but can cause problems being interpreted as multiple extensions, so really, the dash is the best bet.
