Of course it depends on what you need, but wordpress is not even close to the best blog software if you need standard blog features and a site that actually runs without the kind of maintenance problems described. If you want a huge plugin ecosystem and easy theming then yes, it is the best. You just better get caching right because it's going to hit your database 100+ times per page load once you install those themes and plugins.
