WordPress (the self-hosting, WordPress.org flavour). Works like a charm. It's flexible, easy-to-use and performs very well on a mid-range virtual host. It's also reasonably secure if you apply common sense and best practices (e.g. use complex passwords) and don't install plugins indiscriminately.

There are plugins for every feature you could possibly need.

You admittedly have to put in some time for researching and comparing those and not fall for the temptation to install the first plugin you come across for a particular feature.
