[Plugin: Google News Sitemap Generator] Question about this Plugin

I have a quick question. I’m using the Google XML Sitemap plugin right now as my plugin to handle the sitemaps across the various blogs I run. The question now, how does this sitemap plugin differs from the Google XML Sitemap plugin? Are the sitemaps of equal importance -just the same- in Google’s eyes or is this something different?
