One is a consumer program, one is a professional program. If you can afford FCP it comes with all the bells and whistles and if you're serious, you'll learn how to use them. Apple Color and Motion are VERY powerful programs, but I'm too lazy to verify whether FCP comes with them for sure.
Is cost an issue?
