I knew that one was coming
I prefer to look at Awstats for personal use (outside of the CP as I don't know where I will be and on what PC) but if anyone else is looking at site stats graphically webalizer presents history better - showing increase/decrease over months easier at a quick glance. Awstats from what I have looked at only presents charts on a month by month basis.
It'll only be the one domain which runs both.
