CyanogenMod remains my favorite ROM inspite of various other really popular ROMs such as AOKP and Paranoid Android coming up. And recently CM team declared that their latest ROM can be considered stable for everyday use. (As per me it was already stable for quite some time). So go ahead and check out the CM10.1 download page to see if your device is in the list of devices for which the stable ROM is available. Most of the popular devices such as HTC One X, Samsung Galaxy S III and the Sony Xperia Z are already on the list.
About CM10.1: It is a one of the most popular custom ROMs which acts as the base for various ROMs such as AOKP. It is based on Android 4.2.2.
