I look at it from a very personal way.
As long as the negative is 'decent', that is, I can print it in grade 3 (that's my standard grade - 35mm) and get an decent test print, I will look closelly at it and decide - more contrast or less contrast?

That's very much related to the photographer's style and liking.
I did a photo that was plain vanilla at grade 3 - but came to life as a high contrast grade 4.
