>peace
the new empire ended the clone wars and ended the war between the Jedi and the Sith temporarily. It was legitimately more peaceful than before. The rebel battles were much smaller than the clone wars.
>freedom
The galaxy no longer was ruled by local dictators such as Queen Amidala, a corrupt senate, and Jedi cultists. The rule was relegated to a single emperor which didn't interfere much in people's personal lives. It's often overlooked that under the galactic senate, there were many kings and queens. Not exactly a "free democracy"
>justice
The empire rigidly enforced law and order
>security
Crime rates probably dropped under a consolidated government that was no longer busy fighting a clone war
