adw and launcher pro i think are really neck and neck as to the 2 best launchers. really for me lpp puts it ahead with the further customizations and the widgets.
zeam is also very fast but doesnt have as many features as the previous 2.
to me oem launchers are a pita and the first thing i want to get rid of when i get the phone. i like how sense looks, so i have a sense dockbar for lpp, thus giving me the advantages of both.
