Are stat scripts like webalizer accurate?

Or should I just install google analytic on all my domains.

Some it won't be a big deal, WP and all.

But some I got to go into the code ect...

It always seems that the freebie ones that come with Cpanels are way off...is this true? Or am I just untrusting them because "you get what you pay for"...

I guess google analytics is free too...

A marketing buddy says stats don't mean crap, sales be your guide to tell if you are getting traffic. (no he isn't a pirate but he did say it like that).

but I think stats give you good value in what is happening and direction...

Webalizer is only an approximation and will not give you truly accurate stats.
