18-70mm DX vs 28-80mm for Nikon D70

[claude_pt]

I must admit I'm a bit novice in this matter, but I want to make me a personal pleasure in buying the Nikon D70 for mostly in-house portrait photos and family photos as well as buildings. I actually rarely take real landscapes photos.

The D70 is offered in a kit with the new DX 18-70mm or as an alternative a 28-80mm objective.

My question is which objective should I choose of these both and what are the differences as well as on a quality level as on the level for my use described below?

Does someone have experiences or information on this topic?

Thanks a lot
Claude

To be more precise it's the:
28-80mm/3.3-5.6 G AF-Nikkor
vs. the:
AF-S DX Zoom-Nikkor 18-70mm/3.5-4.5G IF-ED
