I will have to break from the group and say I LOVE ADW Ex launcher....
Very customizable and now features the customizing of docks. It still does not have the FB/Twitter or Calendar widgets but those I don't really use. This is a launcher I really enjoy using.
You, and I are in a minority.
I've used LPP, ADW; and ADWEX (subtle differences). Over time, ADW, and now ADWEX grew on me. I just like its KISS nature, and how practical it is.
