This cannot be answered convincingly in the abstract because it depends entirely on the type of object.

  1. One can easily envisage an object that (for example), has to establish a remote connection when created new; and that involves doing a DNS lookup, handshaking and authentication. Whereas if you reset the object it might retain the existing connection, and just reset its current internal state.

    In this case, re-using might save substantial time.

  2. On the other hand, you can also envisage an object that has substantial (perhaps hierarchal) internal state, that resetting might take a substantial amount of time going through setting values back to the defaults. Whereas simply discarding the whole object and creating a new one would be quicker.

The bottom line is: it depends. And your best way to find out is to just time it both ways using the actual class you're concerned about.
