It comes down to personal opinion really, obviously FCP is the software to use these days and there is a reason for that, it's going to allow you to do pretty much everything you'll want to do but as John said, it can be cumbersome and it can get complicated at times but once you get to know your way around it, it does get easier. Premier is going to be a whole lot easier to use, it's pretty straightforward regarding it's menu's and tools etc, you won't be overwhelmed. Premier was the first editing system I used and it definitely helped me learn, so it's up to you whether you go for the quick, simple option or the longer, maybe more rewarding option, either way it's not going to matter which you used once your project is finished.
