It depends on the case. For the defense, a hung jury can be seen as a partial victory if they believe the evidence strongly favored acquittal. It shows that at least some jurors were not convinced of guilt beyond a reasonable doubt.
For the prosecution, a hung jury can be frustrating, but it keeps the case alive. If they believe they can persuade a new jury, they may view a mistrial as a setback rather than a defeat.
In practice, both sides often reassess their strategies after a hung jury. The defense may push harder for an acquittal or a favorable plea, while the prosecution may refine its presentation of evidence or narrow the charges.
