Each fan is given more space than any other ground in the stand and the seats are very large padded leatherette seats. This applies to away fans whether they pay £26 or £64, and we got cheaper tickets when they moved their around £30 (cheaper than Highbury was), so the criticism for not catering for all price ranges is wrong.
You can walk all the away around the stadium with fences or any obstructions, and they have large toilet facilities outside (built with the ground before we had anything like that). You can drinking cans near or go to the pub right outside and they have on street parking if needed off the A1. The tube may get long queues but you are on in 5 mins unlike the trams the tubes are much more regular and they fit a lot more people on.
The concourses are comparable per person to City's and I wouldn't know about the food which probably is comparable too from the description given earlier. It is better to get away from than similarly located grounds with the tube to Cockfosters, much easier than West Ham, Spurs and Chelsea for example. Credit where it is due it is a lot better than the Etihad, and should be the amount it cost , being more modern and purpose built rather than a semi-retrofit.
