I don't think these products are directly comparable. I think Final Cut Pro probably maps better to Adobe Premiere Pro... But even then, it's not a complete overlap. There are things you can easily do in Premiere that you can't easily do in FCP, and vice-versa. In general, I find that Premiere is a bit more powerful/flexible than FCP, but FCP is much better software and does what it does much smoother and much faster.
