As a Sheffield Wednesday fan:
Best: Wycombe were good this year, but some of the best at Hillsborough over the last couple of years have been Plymouth and Southampton. Also having been at a few Stevenage matches, there home support is really good, not so numerous away though.
Worst: Theres so many... MK Dons are (and always have been) awful. This year, PNE were rubbish both home and away.
