I would vote for the binoculars without knowing more. Though I have often been tempted to buy, I have never even looked through any (relatively) low cost night vision equipment. I have questions about the durability of this type of equipment, the gizmo's dependence on batteries as well as how useful it really is at this low price point.
For me, the decision ultimately might depend on some environmental factors . In the winter when it gets dark so early, the night vision might make more sense. If the area is very wooded, the binoculars won't do you much good so again I would lean towards the night vision.
Of course the ultimate advantage of the binoculars is that they would be useful during daylight when the night vision device is worthless.
