The question is "Will Sapiens beat Quicksilver?"

Surprising? Yes it is. Sapiens has, according to me, more familiar user interface than other application launcher. More interesting, Sapiens can detect your mouse circle movement. This mouse gesture will launch Sapiens.

Customize Sapiens
You can click on the Tools icon to open up the Customization Pane. There are many settings inside, such as Activation and Layout, for the sake of your preference.
