Well, I am not the biggest fan of sitemaps, but I do use it occasionally, often when I try to test something related to what was once known as the "sand box" :)

They are great to get your website indexed quickly and to see how it gets indexed, but I have found that after the initial "burst" of crawling activity, Google gets into a routine and crawls your website in regular intervals, regardless of when you re-submitted the sitemap.

Of course, there are exceptions, such as news sitemaps or your website gets updated daily.
