I recently discovered CyStats for wordpress, as I needed it for another plug in I recently installed. I have got to say it makes it easy to see all your stats right here in the WordPress backend. No need to go to your CPanel to see stats etc. A lot is laid out right in your WordPress sidebar.
And for those curious as to how it compares to WordPress built in stats, I can say it is much better, and more detailed. Plus, it is free. I can see it is already doing its job.
Here is a screenshot from the CyStats Time page.
The pages that CyStats has are:
