I've been to 3 out of the 4 Real Madrid aways and the escalator going up has been working each time, but it would be comparable with Newcastle and where I sit in the Etihad SS3 if it meant a walk up the stairs. There is netting or a screen at pretty much every away in Europe, so if thats a problem then maybe give European games a miss.
We're allowed to have different opinions, but Lokeren was a temporary stand which no longer exists, so I think yours is quite objectively wrong. You may well have had a better experience in those but I think you will be in a minority of one to say that either is a better stadium in any criteria.
