we have the Nikon 14x40's. I have not used any other brands so cannot give a comparison. As far as stabilization goes, they have two levels, land and sea. In my experience, land
compensates for the "jitters", whereas sea
adds additional compensation for movements like swells, etc.
They do use batteries rather quickly especially if you're sitting at anchor
and perusing the boats (bikini clad crew) as they come in to anchor!
We bought them because they are waterproof, center focus (can adjust for vision correction), and really worked.
While they are expensive, we have never regretted buying
them as they are a pleasure to use.
