Can someone explain me the difference between this rom and Virtous Inquisition?
And, is this rom stable enough for a daily use?
This ROM is 100% AOSP, no traces of Sense.
VI is a desensed ROM, meaning most of the the Sense elements have been removed. There are still some Sense bits hidden in the menus for example.
OpenSensation is still being worked on while VI is pretty much final build.
And yes, its very stable.
