It really doesn't make any difference to the final product, just choose the format that is most comfortable for you and run with it. For all the Premiere bashing I have done in the past, I have to admit that 6.0 isn't just another wanky upgrade, but a monumental step forward. The boys in San Jose have been doing their homework and have turned out a pretty decent product. It's a win, win situation. If you are trying to decide between Premiere and Final Cut Pro, there are a lot of features and options to consider.
Price is definitely a consideration.
That's a pretty steep difference for two products that do virtually the same thing. As I have said in the past, download a demo from the web and try it out for yourself. After all, you have to live and work with the product so it should meet your professional needs. As for me, I'm still hooked on Final Cut Pro and in the near future we will take a look at Apple's latest offering, Final Cut Pro 2.0. So until then, I hope you find peace and prosperity.
