Has it improved? topic

I owned a T705, it was my phone and tablet, i loved it.
However, the camera was bad, and the whole Interface was very jittery.

I understand that this device is not getting updates from Samsung, but man, i sure miss the screen real state, also beautiful.

Have lollipop custom roms reached a state where they improve over samsungs touchwiz performance?
I am considering it, alas i read that a new Tab S might be coming.

Thanks.
