Premier Pro versus Final Cut Pro
In my experience both Premiere and FCP will do pretty much the same thing.
They have similar lay outs and, I would say, are as easy to use as each other. I first used Premiere when I had a PC but moved to FCP when I went to university and got a mac. I find it a lot easier to edit with FCP and the transition to other programs are very simple and effective (file > send to > Color/Compressor).

If you have a mac I would suggest buying the final cut pro studio. It comes with Motion, Soundtrack Pro, DVD Studio Pro, Color and Compressor. Everything you need (pretty much except Adobe After Effects). And if you have a PC then go with Premiere. That's my advice.
