hese all do about the same thing optically. At normal shooting apertures in the center, they are all about as sharp as each other and the reference lenses at most focal lengths.
They cover different ranges and are different sizes and cover different formats. Nikon makes no 28-450mm zoom for FX, which would have been the analog to the 18-300mm DX lens.
All these lenses can make knockout photos 5-feet (1.5 meters) wide, seen at the same distance as your computer screen. People who spend a lot of time worrying about lens sharpness rarely spend time worrying about what makes a good photo, so they rarely do. Don't become one of them, get out and shoot!
When I spend more time looking at the master files for thee shots on my dual 30" monitors, I realize that as plastic zoom lenses, there is often more variation from shot-to-shot with each lens than any consistent and absolute variation from one lens to another.
All these zooms are made using the same technology, and pretty much make the same pictures.
