I can't answer your question directly but the fact that Switcher requires "Aero" support, which Dexpot does not, may mean it is capable of a richer set of visual transitions.

I've been using Switcher for a long time. That's the most elegant Expose clone for Windows I've encountered so far.

I wonder if there's a way to make Dexpot's Window catalogue more elegant and look better.

1. When triggering Window catalogue, it will be nice to have a zoom out effect.
2. Switcher does the background very nicely - fade it darker without making it gray (retaining the colours of the desktop wallpaper). Gray doesn't look that nice.
3. The gray side borders are an eye-sore. I believe it's because of the top bar which resized the wallpaper. I can do without the top bar - just to make the desktop fit my screen without borders.

I suggest the developer to take a look at the freeware Switcher. If it looks as good as this, I'll make the switch permanently to Dexpot!
