Which Camera lens is better for the Nikon D90?

Better is only a matter of opinion. People have different needs depending on what they shoot. Myself, I'd go with a 28-200mm lens.

Matters what you want to do with it.a good prime lens would be the 50mm f/1.4, a good macro is the 105mm, a good all around purpose lens is the 18-200mm etc etc etc

I would consider Sigma 18-50mm f/3.5-5.6 DC HSM Wide Angle Zoom Lens for Nikon D90, D80, D70, D60, D50, D40, D40X, D5000, D3000, D700, D300, D200, & D3 Digital SLRs *

Compact dimensions offers superb handling and mobility.
The use of aspherical lenses provides correction for various aberrations
