A fully debloated kk-Rom was great with a good tweaked Kernel with OC/UV-features. Than the ability to chance the screen-resolution to fullHD for better gaming-performance like in SDBAGS Cromi-X Rom for Asus tf701t. ES File-Explorer, Xposed Framework as system apps. Than the old webkit-android-browser(aosp) with bookmark-sync, like in Scroslers Clean-Rom.
And I think there is a lot more to make KK better.
