Hello sporob, and welcome to the friendly Camera Labs forum!
To enjoy your stay here please have a look at the house-rules
You've certainly read my review of the 28-300 over here
The 28-300 is on average a bit better than the 18-200, but - as i warned in my review - you'd certainly want/need something shorter than the 28mm on the wide end. That could be one of those 10-24mm lenses of which Nikon also has one on offer, or a 12-24mm would also do fine.
But still you might be finding swapping lenses a lot if you are in a situation where you need something in the range of 18-40mm.
So my personal advice:
- If you're pretty sure that you'll stay with a DX body in the foreseeable future: get the 18-200
- If you're thinking about upgrading to an FX-body sometime and
you can muster the financial resources: get the 28-300 and complement it with some ultrawide zoom at the short end.
