Thank you for all your replies, and I'd like to apologise for my sarcastic reply to darkosaric. It looks rather ruder now than I intended when I wrote it, regrettably. I'm sorry.
If I may try to qualify my question a bit - I'm not interested in which films are objectively and measurably better than other films, I know that such a question is mostly meaningless. These quotes touch upon the question I'm trying to ask:

If different films have different character, there must be a difference, if subtle, in the final image. Is it the spectral sensitivity? Contrast? Latitude? I can read about differences and kind of understand descriptions of a film's properties, but it's so much easier to understand with two pictures side by side.
