And here are my stats for January 28th with Google Analytics:
Why might my statistical results be different between Google Analytics and CloudFlare's analytics?
On one side, Google Analytics is very reputable and been there for years. On the other side, CloudFlare is a CDN, thus your site's content is distributed around their servers around the globe, so they claim that their analytics are more accurate than other services (implying GA) who rely on JavaScript.
Note: Google Analytics is installed on pages automatically by Cloudflare. They inject it on all pages even 404 pages.
