Pro Native to OS X
Spotlight comes packaged with OS X and iOS.
Con Limited customization
Allows for very little customization, not theming, and no custom scripting.
Con No longer launches applications at all in Sierra
After updating to Sierra, typing an application name in Spotlight results in "No Results" or random wikipedia matches. True even after reloading com.apple.metadata.mds.plist and adding/removing "Macintosh HD" on the "Privacy" tab. Launchpad still works.
