I've been using Clicky for the past 5 years, and I think it is much, much better.
Clicky is a realtime analytics platform. That means there is no waiting to see your analytics reports. As soon as a visitor hits your website, it will appear in clicky.
It tracks everything you could want – visitors, content, entrance/exit pages, bounce rate, referrer etc.
But what I love best about clicky is its interface – it has what I believe to be the very best interface of all the analytics programs. It is simple to use and data is displayed in a logical fashion. Clicky is the best Analytics tool.
