I grew up opposite Maine Road, so it's also a big part of my childhood that I truly miss.
What I would say when comparing the two.
Maine Road was a total match-day experience as the majority converged on it and had their own personal rituals and hangouts.
The Etihad, however, while the scene of some incredible history, offers zero match-day experience, but the club contrives to create one with a total emphasis on monetizing each supporter who attends.
This ensures thousands stay away until they actually 'have to' make their way towards the stadium.
The Etihad is only a magnet for the actual football, which makes Maine Road a superior all-round experience for me.
It was the beating heart of a community that was happy to have City there to represent it.
The immediate surrounding area of the Etihad couldn't give a shit.
