I prefer "G" to "E" due to better reliability in cold weather and high humidity. The electrical contacts (that control the aperture in "E") seem to stop working regularly when photographing ice formations on the sea for me, or where there is open water and temperatures are cold enough (-20C +- 5C). The first hour of shooting by the open water is usually problem free but I want to shoot for several hours and usually the "E" lenses start crashing by then (overexposure is typical, camera body shows error and won't take shots reliably). It's not a big issue as usually things start to work again by removing the lens and battery and putting them back in, but it's enough of an annoyance to mention. I don't think Nikon was wise in confounding the F mount with a new system that was not properly tested in difficult field conditions. Perhaps the electrical contacts are not shielded from the outside air well enough.
