I have been all too pleased to move away from the ruby based compiler and just use a pure grunt workflow. It is vastly faster and lighter weight.

From what I understand there are some limitations to the implementation, but I haven't encountered any so far.

The few issues I've run into are that I can't use Compass and I can't have Source Maps (yet).

Instead of Compass, I've switched to using Bourbon (bourbon.io) but may consider just using Auto Prefixer in future dev efforts.

Source maps I can live without since I haven't gotten used to them. I know it's in the works or at least being thought about: https://github.com/hcatlin/libsass/issues/122.
