I've been using ADW because I like the easy cookie cutter themes but I notice it lags sometimes when switching between screens and sometimes icons and widgets will disappear then reappear as the screens load. I tried the free version of Launcher Pro and as I was setting up the screens it felt like it was smoother. But that could have been because I didn't have anything on them yet. I know most people here use Launcher Pro - is it because it is faster or smoother? I can almost get away with using the free version but I need to be able to resize widgets.
