I just installed Launchbar 4.3.2 and have Quicksilver installed I believe it is build 3800. Anyways I use it mostly for launching apps and open files. I like the extensibility of Quicksilver but Launchbar seems faster to me. I am not sure which one to get. I would like to know which one is better with the computer resources since I am on a macbook and not a macpro, macbook pro or an imac. What do you guys prefer and what made you pick either launchbar or quicksilver. Thanks
