Would the Nikon 18-200mm VR or the Nikon 18-105mm VR serve me better?

Planning on purchasing the Nikon d7000 which will be my first DSLR. The one from Costco comes with the 18-200mm VR II lens and is more expensive. The other kits I've seen come with the 18-105 mm lens.

My main uses with the camera are close up & macro flower and nature shots as well as landscape and family use… Hopefully to capture some nicer looking portrait shots of my kids as they're out and about. However they don't sit still for very long so the use of zoom & action may be needed as well.

Which lens would serve me better? The 180-200mm or the 18-105mm?

The 18-200 mm is perhaps one of the best single lens solution available at this time.

It replaces the 18-55 and 55-200 mm lenses.

The 18-200VR. It is the walk-around lens on my D300.
