Which is more accurate? site: or GWT?

[nicole.healthline]

when viewing urls in google's index, is it more accurate to refer to site:www.domain.com or google webmaster tools (urls in web index)?

I would venture to say GWT for a few reasons:

1. The site command doesn't always show everything,
2. The site command is available publicly,
3. The GWT has to be verified by the owner, hence they should show you more accurate data.

I agree with Steven on everything he said. Google has been putting a lot of emphasis on making sure SEO's are utilizing GWT as a resource for usability and correct data.  I'd use that as your primary source.
