Villa's run to the Carling Cup final saw an even more thrilling game when Blackburn were beaten 6-4 in the semi-final, and O'Neill conceded that his side had produced some dramatic football in the cups this season.
He said: "There have been some great games this season and that is what cup football is about.
"We go for it and so have other teams against us. Reading's part shouldn't be underplayed.
"They were fantastic and played it like a quarter-final from the first whistle. They were terrific."
Reading boss Brian McDermott reserved praise for goalscorer Long, who had sat out the previous four games through suspension following a red card in the fifth-round tie with West Brom.
