Hello to all sifus of the GS4

I'm currently interested in helping my sister to flash a custom ROM on her GS4 (GT-i9500 variant). I'm looking for something that's stock android (CyanogenMOD, AOSP etc).

Any suggestions to what is the best and most stable stock android ROM available for the GS4 at the moment?

I don't need much fancy features such as those seen on ParanoidAndroid. My priority is for the ROM to be as smooth and as stable as possible! (of course, i am aware no ROM is 100% stable )

Many thanks and all suggestions appreciated!
