The original 4.4.2 Stock ROM is just great and very, very easy to use even though it has so many cool features (Infrared, knock on,...).
e.g. For the LG G2 it's quite some work to get the IR blaster to work with other ROMs and i think it's the same here.
I wouldn't install any other ROM! (Not hear this from me often!) It's perfect and just works! I installed the xposed modules, which makes it even better.
