I switched to ProcessWire [1] a couple of years ago, and haven't been happier.

It succeeded to do what Drupal tried but never managed to do:

It is both extremely stable and extremely flexible at the same time.

By having an extremely generic and small core, combined with an extremely powerful programmatic API (basically jquery for data from the CMS, but better), you don't need fiftyeleven modules to achieve some basic tasks.
