OS!
... No troubles in a Mac setup.

LOL - Don't support a myth by repeating a marketing lie.
There are plenty of issues. Whether, it is more than a pc or not, I don't know. But, believe me, there are plenty of issues with a mac.
I would say, if you are use to a PC stick with the PC.
I do love Final Cut Studio - but the last upgrade to it seems like Apple has switched their focus to their iGadget stuff - therefore I am wondering if the Adobe suite might be the better alternative.
Also, with so much emphasize placed on the iPhone, iPad, etc. they are shifting resources away from the Mac OS.
And the new machines that were released, as so many people pointed out, are really not that all that great of upgrade. They certainly are not "Pro" machines - more middle of the road - as Digital Skunk pointed out.
I love the OS, but I don't think it so far ahead anymore. I think MS did a great job with Windows 7.
And with an apparent war ahead with Adobe (even if you use FCS, you need AE), you might want to just stick with your PC.
As an aside - Plus, where the heck is Blu-Ray on the Mac?
