There is not any reason to argue over who gets indexed the fastest but I will say that with the plugins wordpress has you can set up your site to do many task automatically saving you a tremendous amount of time all the while getting your new post indexed quickly.

In my blogs I use the auto ping group that was listed before as well the seo plugins that work well with Google webmaster tools. Add in my auto updating sitemap and boom I get to basically sit back and watch my new site grow on a daily basis.

Focusing on keyword search engine ranking is really a whole new animal altogether from just getting your site indexed.

But when it comes to time saved I have not found a better system than wordpress.
