Best Statistic plugin?

In your opinion what is th ebst stat plugin for WP? I am using kstats reloaded which is outdated and I am not sure it is giving me correct stats. I have tried WP-Stats-Dashboard which simply slows my site down. -its a great plugin but there is simply too much going on with it all at once. Since that was installed I also had to have WordPress.com stats installed. Not sure that was right either and really who needs to stat plugins?

All this being said I am not a programmer so I am not as intelligent in this as I would like to be. Any ideas?
