This has been asked and answered so many times, in so many ways.
I will say that my personal experience, having used PC, Amiga Toaster/Flyer and Mac (since its desktop publishing beginnings) now exclusively Mac & Final Cut Pro & its associated programs, even the iMovie, iDVD, etc. series, I am comfortable and pleased with the ease of use, stability and support experienced for the investment.
You will, however, once this post gets a few more eyeballs, receive the whole gammut of comments, pro & con, regarding a smorgasboard of platforms and software. I suspect that should you opt for Mac-based production editing, you will have an overall pleasant experience and no serious regrets.
