I use scale because it's easy and fast. I've been using it for a long time now. The genie effect is just annoying. It was really cool when I first started using OSX, but now it just seems real pointless.

I included the 'Suck In' effect. You can get this from a couple of h4xx0r apps. I don't use it, I prefer Scale.

I use Scale for the same reasons. It's good looking, fast and simple. Kind of like the window zoom effects present in Jaguar...
