Match day experience is far more than the view from your seat, and legroom. It's the location of the ground, proximity to decent facilities like public transport, town/city centre, atmosphere.
Unfortunately the Ricoh is rightfully situated at the bottom of the pile. I've been to games in the Spanish 4th division which are a better match day experience overall.
I do take issue with the list though. Liverpool and Man Utd near the top?
For me the top few would be Norwich, Forest, Barnsley, Brentford, Everton, Sheff Weds.
Despite the current hatred for Sheffield United, in terms of overall experience it's a lot better than my eyes than the Ricoh. Although for such a 'massive club' the atmosphere is usually startlingly poor.
