The consensus in this post is wrong.
Cyanogenmod offers a lot more privacy. It doesn't send anything at all unless you opt in for usage statistics and/or network based location and/or you install an extra app which does send your data to its remote servers. On the contrary, the default Android has numerous Google services running constantly in the background, and, assuming the worst case scenario, Google will collect a LOT:

It should be noted that if you choose to install Google software on your CyanogenMod, the privacy benefits will be gone or at least reduced. I personally have APK's which I gathered from several sources on the net, and I install my apps from my own APK's without ever needing Google Play Store or any other Google product. This means I am 100% Google free and I gain all the privacy benefits of Cyanogenmod. The drawback is not having Playstore, but for me it's worth it.
My Google apps replacements:
Google Maps > Osmand
Google Talk > Xabber
Mail > Cyanogenmod 7's stock IMAP client
