I will go for the Widescreen versions every time!
I remember many years ago, buying the STAR WARS trilogy on video in the widescreen format after seeing A NEW HOPE playing on a television screen at my local HMV, and noticing the difference this format made. The film presentation was exactly the same as I had seen in the cinema on their original release and much preferred to the pan and scan versions as shown on television.
Talking of television films, I wish they would show them in the Anamorphic Widescreen layout so that everybody would be happy. We would have the FULL picture and no black bars at the top and bottom of the screen, which I understand some people hate, although I have never had a problem with them.
