Try both before you buy would be my advice....
If you want, we have a Nite Site NS200 demo unit on our 7 day NV trial scheme you are welcome to have at home to try with no obligiation to keep it, as it is a dedicated demo unit (conditions apply)
We have lots of other NV units available for demos from Gen 3 Image Intensifier devices, down to hand held digital NV.
Cheers
