Definitely better ratios around the moon.
Opinion will be divided on this, but if you do a long exposure at night, the sky is still blue, it's just that our eyes don't pick up colour so well at low light levels. The sky is, after all, still lit by sunlight. It's just that the sunlight is reflected off the moon and there's a lot less of it. Having a neutral sky and seeing colour in the terrain/objects looks a bit wrong. A little bit of blue in the sky will still look like a night scene
