18-70 is certsinly better built, and focuses quicker.
Sharpness.. sorry I didn't compare... seemed quite close unscientifically. The 18-105 VR has more CA (seems typical of new Nikon lenses, leave it uncorrected optically, let the JPEG engine correct it)
I prefer the 18-70 DX personally.
18-70 is a corker,should never have sold mine.
Do you a Sigma 17-70 would be a better choice or not?
As Sigma has macro as well.!
Sigma's a nice lens. Be warned its not a "true" macro lens i.e. 1:2.3 reproduction rather than 1:1. Still good for shots where you want to focus up close...

what's CA?
Just picked up a Sigma 17-70 myself and have to say I am very impressed with it for the price. My copy is very sharp and it is smallish and light. Perfect walkabout for my up and coming holiday. F2.8 at the short end and semi macro capabilities are an added bonus.
18-70mm undoubtedly. I got mine with my D90 as opposed to the kit lens, and I love it!! Very sharp, and suprisingly wide too
