As stated, cPanel logs will display every request that was sent to Apache, this includes crawlers, bots, etc. Whereas google analytics will not include any of this. For example, one site I haven't launched yet but it is online, received 2.7 million pageviews this month (80,000+ pages indexed), but in all actuality, there has only been truly a couple thousand page views. The majority of the page views were google/bing/etc bots.
