Scid vs PC or ChessX?

which one should i download and why?

ChessX's interface is MUCH nicer. They have largely the same featureset, and I'd take ChessX for its fantastic usability. I also love the way it interprets moves. You'll know what I mean when you mouseover the board in ChessX.

However, I'll also say they're both free, so why not just given them a go? :)

Thanks Hellball :)
