Default Which Android version you like most on XPERIA Z1?

Sony Mobile just released official Android 4.4.4 KitKat to Sony XPERIA Z1 and my question is, which version was the best for you. I mean that Android 4.4.4 is really best now, but i want to hear you experiences. If you want to install latest Android 4.2.2 Jelly Bean/Android 4.3 Jelly Bean/Android 4.4.4 KitKat, you can use link below... It is Central Europe version, so without any bloatware.
