As a pure observer these days I was paxing from SIN to GVA a couple of weeks ago to pick up the bosses jet and had a ride on an EK380. As it happened, I recognised the Skipper and said hello at the gate in SIN. Later on before departure I said hello and in the course of our 5 minute chat he showed me the tech log
Without going into specifics, the jet was about 2 years old, but had the sort of problems I would have expected of a much much older airframe, typical Airbus, cheap to buy...but an expensive proposition to maintain.
Whilst all this is subjective, the thing just looks and feels poorly built, the upside is that it's quiet so I suppose that's a positive.
