It depends on your needs.
The problem most people have is that FCP went from a fully professional suite to a prosumer product. This is because Apple started from scratch for this version and a lot of functionality is still missing.
If you are a beginner or amateur, FCPX might be great for you. If you need to ask why it's so bad, you probably haven't run into the limitations yet. I would not worry about what other people think. FCPX is definitely way more streamlined and intuitive than Premiere. For basic editing tasks, it's quite good actually.
