I've tried all the three main launchers and I like the LAuncherPro and GoLauncher.
I really, really like the LauncherPro, its amazing, but the GoLauncher is fantastic too, much more customizable... but I still like the LP more. I wish it had horizontal scrolling of the apps tho, I find that much easier and more organized than the vertical one... oh well, maybe they'll put it in in the future.
