Hi there pswissoz, I know we all tend to have different priorities when travelling, so this may or may not be relevant to you : after many years of Emirates experience (albeit not as many as some here .....), my thoughts are always about the type of crew I'll find onboard, rather than the exact variation of equipment type !!
For me, it's the crew - over and above everything else - that determines the 'quality' of a flight.
And on Emirates, I think it's fair to say that the crew can be anywhere within a range encompassing the exceptionally good to the distinctly average........
PS. very much doubt there will be any difference in the ICE or seats across A380 variants, but others will confirm.
