What is the best Stats Software?

[MyDigitalpoint]

Thank you guys, I have plenty of time this weekend so I think I'm gonna give it a try to both JMP and Piwik.

Like I said, I prefer to manage on my own every aspect of the service, plus is more exciting to me experiment with an installation that having to learn how to navigate inside a present service, in example, I'm still confused with Google Analytics (for years) forgetting always where to retrieve the piece of code when changing templates made me forget to retain the code offered first hand after setting up a website.

That's terrible to me and annoys me, really..
