Got the Android 4.3 update and not happy with it? Still think it lags a lot or want a change? Well I just want to say, I have flashed temasek's latest CyanogenMod11 which is based on Android 4.4 and looks very similar to the Nexus 5 UI. I've had this ROM for a few days and I absolutely love it! The UI is very clean and it doesn't lag at all unlike touchwiz, it is also updated daily.
Here is a link to the thread: [CM11][4.4][ROM][KERNEL][NOV27] temasek's UNOFFICIAL Build - V10 (r3p2 mali) - xda-developers

Note: You must have root access to flash this ROM, you also need a CWM (Clockwork Mod Recovery). You also need to flash Gapps 4.4 (Google Apps) Without this your phone will be messed up, here is a download link for it
