EKs IFE is pretty much dictated by the type of aircraft you fly on. If you are on the A345 and 777 ERs you will definately have the ICE system.
The 330 and 343s dont have the AVOD system. The non ER spec 777s dont have it either, although I believe it will be retro fitted.
I have experienced both , and I must say the ICE system is by far the superior of the two. I never had any reliability issues with it. I really like the mood-lighting and improved seats on the 77Ws as well.
