If you need to share footage with an FCP user, you are better off using FCP. And apparently there are export issues with no OMF support in Premiere Pro.
So, basically, a one man shop can do anything with Premiere Pro that he can do with FCP, but sharing is a different issue.
Me? I use Premiere Pro successfully and have no urge to switch over. But I am not inclined to say bad things about FCP. Both programs have shortcomings and features that the other does not have.
