Personally I'd stick with the static site generators.
If you get something like wordpress installed on your own server, you now need to then commit doing the upgrades for it. I've been burnt enough times with self-hosted things like this where I missed an upgrade for whatever reason (real-life etc) and the site was hacked very, very quickly. There are ones that auto-update themselves but I have found that those have their own issues so cannot be relied upon.
Static site generators tend not to have this problem.
