I inherited a 3'-4' chain link on the sides and front. It's been fine for the 40 +/- years it's been up. (I've been here 23 1/2.) The back is the schoolyard's 6' chain link, which is closer to 5' on my side. I'd prefer black, which is less visible, but I like the air flow and being able to see.
The privacy fences in this neighbourhood don't seem to last long--the poles rot, the wind blows them down, and so on. The snow gets trapped in weird ways and takes forever to melt on the shady side.
If I lived in the country, I might opt for what dante2zoe has, but in the city, I'd go with black chain link. ETA: If I could, I'd go with painted/powder-coated rather than vinyl-coated, since I expect it would hold up better here.
