I know I'm biased (and I guess it was a bit one sided) but I thought the L2 playoff final was the better watch of the three. Wycombe/Oxford was very ordinary and even though you could see both sides (particularly Fulham) were trying to play good football in the Championship play off it was no great spectacle.
The second leg of the Cobblers/Cheltenham game was the best watch of the play off matches of the whole series.
Was thinking this while watching the Championship final. Even though we trounced them it still felt like the best watch of the three.
