Windows Vista's Aero Flip3D vs. Otaku Software's TopDesk Flip3D

Trying to emulate Vista even more, I have downloaded and installed Otaku Software's "TopDesk" that has a function just like Windows Aero's Flip3D that comes with Vista. For some reason, I prefer Vista's Flip3D's looks to the one made by Otaku Software. Here are two screenshots; first from Windows Aero's Flip3D and second from Otaku Software's TopDesk Flip3D.
