Hey German Dude,
The best 4.4 ROMs in my eyes are carbon & Luiquidsmooth.
CM has regular updates, lineup Linaro mod CM is supposed to be extremely optimised on the hardware, maybe it's the best way to go.
I am waiting (and hoping) for Sailfish OS and currently using simple CyanogenMod 10.2 (android 4.3). It's really easy going. Fast, smooth, stable, statisfying
