I like iMovie just because I'm so proficient with it and really know what I'm doing to take full advantage of it and ALL that it can do. I don't care what the program looks like as long as I know how to use it and it works to do what I need it to do.

That being said, the show should hopefully switch to being edited in Final Cut sometime soon (that is of course, if I learn Final Cut and like it better for the show :)).
