Some people love it, others hate it - whether it's the best piece of software for editing drama is mostly subjective personal preference. It's been used to edit big feature films for years and a lot of professionals seem to like it, so it must be quite good.
Avid is probably more popular among professional users - whether that makes it better or not in your eyes I don't know. Premiere Pro has gained traction in the past year or two but is not yet as widely used as the other two - a smaller user base may or may not be a disadvantage for you.
The biggest restriction of Final Cut is that it will only run on OS X - if you need to share project files between Mac-based and PC-based editors, this could be a problem.
