DDSitemapGen or Google XML Sitemaps

Hi guys im looking to make an autoblog and one of the things i realised i'll need to get decent a decent space on google is a site map. As far as i know the two main sitemap plugins for worpress are DDSitemapGen and Google XML Sitemaps, is there one that you think is better than the other or easier to use or maybe it has more advanced features. Any help in comparing and choosing between the two would be greatly appriciated.

You need both, dd sitemap is for human, google xml is for SEs

o right lol that clears things up for me thanks alot i feel abit dense now

Right Dunggxvn, but dd sitemap is also a page well indexed especially for new blog.
