Ask HN: Which is the best static blog generator?

I've been running my blog, apas.gr, on WordPress since 2008.

I now want to start a new subdomain kind-of blog, for notes and more general stuff. But I'd like it to be based on a static generator like Jekyll or Stacey.

So, which is the best static blog generator out there? Preferably writing posts with Markdown.

Thanks, HN.
