SuperNexus 4 ROM brings pure Android 4.4.2 KitKat experience, like the Google Nexus devices, on non-Nexus devices such as Samsung Galaxy S2, S3, and S4. The ROM is built entirely from Google’s AOSP source (KOT49H – Android-4.4.2_r1), so there is no difference from the official KitKat ROM, except special optimizations necessary for ensuring compatibility with the hardware they run on.
