After going back and forth between Quicksilver and Launchbar for a while, I eventually settled on Launchbar because I found it to be a bit faster. I think Quicksilver is more powerful, but I never really used the additional capabilities so it ended up being a pretty easy choice for me.
Even after Spotlight was added to OS X, I stuck with Launchbar because it takes a few less keystrokes for many tasks and it has search templates (so searching Google, a dictionary, or a thesaurus requires only a few keystrokes). Quicksilver can also do something similar, I'm not sure about the other options.
