I'm still comparing keywords in URLs vs. no keywords in URLs, but with no regard to static or dynamic.
To your point, I could have used static vs. static and dynamic vs. dynamic examples such as:
mywhateverblog.com/page1.html is not as good as mywhateverblog.com/red-widgets-in-texas.html
mywhateverblog.com/?p=595 is not as good as mywhateverblog.com/red-widgets-in-texas?id=595
From Google's own SEO Starter guide [1]:
"Use words in URLs! URLs with words that are relevant to your site's content and structure are friendlier for visitors navigating your site. Visitors remember them better and might be more willing to link to them.
Avoid using lengthy URLs with unnecessary parameters and session IDs; choosing generic page names like "page1.html"; using excessive keywords like"baseball-cards-baseball-cards-baseballcards.htm"
And from Google's Webmaster Tools page regarding URL structure [2]:
"A site's URL structure should be as simple as possible. Consider organizing your content so that URLs are constructed logically and in a manner that is most intelligible to humans (when possible, readable words rather than long ID numbers). For example, if you're searching for information about aviation, a URL like http://en.wikipedia.org/wiki/Aviation will help you decide whether to click that link. A URL like http://www.example.com/index.php?id_sezione=360&sid=3a5e..., is much less appealing to users."
