I really want to test the ICS Launcher for you, but there are just a couple problems I have with it. The first is locked features. A few sub-menus in the launcher settings are locked by popups asking me to pay to unlock them, and I can get similar features (based on menu titles) for free with Go Launcher. It's really smooth and looks attractive, but so are other, freer options on the Market. Also, I would really like the ability to control how many homescreens I have. I personally have only ever been able to fill up three homescreens at any given time, and having those two extra screens sitting there doing nothing with the ICS Launcher just bothers me in a way I can't really explain. Besides that, if I see any bugs or have any other complaints, I'll let you know.
Oh, and I kept meaning to mention this but kept forgetting. I love the silly, sci-fi themed installation text.
