Cm12.1 has most of the features present already, when we compared it with the android M technical preview released for the nexus devices.
AOSPA (a.k.a Paranoid Android)
Aospa (Android Open Source Paranoid Android) is from one of the custom ROM that exhibited new introduced features like DSB (dynamic status bar), heads up notifications, pie controls & immersive on the platform of custom android development which made the following ROM user’s favorite on kitkat!!. Now paranoid android is the most stable official ROM based on AOSP after Cm12.1 for Redmi 1S based on lollipop. It is still in Beta stage so we can expect more new customization options adding up with incremental OTA updates. Till then it lacks all the customization options as compared to the Cm 12.1, in nut shell we can say that it delivers the stock Google android lollipop experience!!
MOKEE Open Source
Mokee is another open source custom development on top of android platform that presents loads of customization options under the hood. Its the next nice and stable ROM for Redmi 1S running on top of cm 12.1. Lots of updates hit the device weekly which users can flash including the nightly’s. When compared with the Cm 12.1, Mokee leads in the section of customization but Cm 12.1 leads in the area of stability and battery backup.
Battery backup: Rom has an above average battery backup.
