I've done a lot of genealogy work for my family name and have used http://newspaperarchive.com/ extensively. In comparing a few quick searches, the Google Newspaper Archive is not even comparable. We're talking 2 irrelevant hits for Google Newspaper Archive vs. thousands of relevant hits for newspaperarchive.com.
And newspaperarchive.com only has a fraction of the newspapers in the country within their records. There is definitely a lot of room for improvement in this space because it's such a large task.
You know you are comparing apples to oranges? Google's archive is free and open.
I'm not comparing Apples and Oranges. At worst what I'm doing is comparing store-bought Oranges in very good condition to free Oranges you could pick up off the side of the road that fell off a truck two weeks ago and are half way to rotten.
