Replying to What is THE best video editing software?

I'm becoming tired of the extent that I can edit footage in Windows Movie Maker and iMovie(is it iMovie? I forget). They have basic special effects which was good at first, but now I'm looking for a program with a little more advanced techniques and effects which will put my unique signature on whatever video I create.

I've heard Sony Vegas was a good one, but is there a better one? What do some pros use to edit footage? Suggestions and help are appreciated.
