Do you connect your AdSense and Analytics accounts?

I connected my AdSense and Google Analytics accounts a couple of years back, so I've been receiving AdSense numbers within the Analytics control panel ever since then. However, the numbers there are always slightly off what I see in the AdSense main control panel.

How accurate are the numbers in the Google Analytics window, do you think?

AdSense can count page views outside of your sites, such as in Google cache page views and similar page views in other search engines, they will never match 100%
