I much prefer LaunchBar over Alfred. It looks and feels like more native to macOS to me than Alfred.
I also use it for for file navigation and find it better than Alfred. The ability to select a file or a few files, invoke instant send, and then copy or move them to other folders depending on which modifier key you’re holding down (Option to Copy, Command to Move etc.) is something I can’t do without, and ties in with macOS.
I agree that Alfred seems to be more actively developed though, and the forum, shared workflows etc. does make LaunchBar start to feel that it’s only being maintained versus developed.
Because of this I’ve started to try Alfred again, but it soon became clear why I like LaunchBar so much. I don’t like the look and icon style versus LaunchBar. Alfred’s look pretty ugly versus LaunchBar’s more macOS look and feel. I like how easy it is to create custom Spotlight searches/filters for specific file, file types etc. In Alfred, but I’ve still managed to the same thing in LaunchBar (admittedly with more work).
I’m hoping that the devs are working on updating LaunchBar instead of just bug fixes, but I’m not optomistic.
