SL Expose is much better imo, although blue indicator and grid layout can use some improvements.
New Expose enables small windows (such as file copy dialog) to be readable and clickable by making it bigger. It think this is a good trade off for visual cue for relative size, especially since titles are always visible now.
Also, in Spaces Expose, it is big help when locating a window, bigger size makes smaller windows easy to click and titles are making it easily recognizable.
