Replying to Best -video- post processing programs?

So.

I just need a simple list of the best video editting stuff out there. I always here people talk about different programs and what not. I just wanna know what you use (and why) and if you like it. I'm on Mac btw.

The ones I know are:
- Sony Vegas
- Final Cut
- Adobe Premiere

Those 3 seem to be the main things. But like, what do they do? Is it only arranging the movie? As in cutting/pasting etc, or is it also deinerlacing, color grading, blablabla. Like, are they programs that can used alone (without the help of other programs, plugins don't count) to make awesome videos.

Let's make it a bit more personally. What does our beloved eheath use for video editting?
