An original user of QuickSilver, I quickly got hooked using LaunchBar. To my mind, far superior to the alternative like Alfred (which I have supported from the start). The onboarding experience is great - and standard use is just easier than Alfred. Meaning that simple functions just work whereas at the moment, just launching an app leads to an unexplained bug. The Workflow but sounds great, but Launchbar (and now Shortcuts on the Mac) kind of negate that advantage.
