In the UK, full-screen versions are rare. But even if I had a choice, I'd go for the widescreen version every time. I'd much rather see the whole of the picture, rather than have it cropped for me.
So, I ordered the widescreen version (even though it's the only one available on PAL in the UK) but if I'd ordered the NTSC version from the US, I still would have gone for the widescreen format.
