What your requirements? With Google rendering JavaScript any static site generator is probably going to be better. If you need crud functionality any number of hosted and open source crud providers are available. Or just use a hosted site builder. They are all better at this point.
Static site generators are just fine for personal blogs. They don't fit the bill at all when you have a group of people all writing on one blog and you need things like access controls and media file management.
Also, not sure why google rendering JavaScript would have any effect on static site generators.
You can use SSGs with GitHub for multi-author blogs. Prose.io makes a nice writing interface for GitHub content. If you hook it up to something like Travis CI, the site can be regenerated automatically on GitHub commits.
It's a bit complicated compared to just running a WordPress instance, but it works pretty well.
