If the fight is good of course it's better. The roar of the crowd will overwhelm you. If the fight sucks balls then it's the same exact ****, plus, at the end you'll feel like you just got majorly screwed out of your cash.
To be fair Froch - Dirrell was a stinker but I still had a brilliant night, the atmosphere was fantastic. It helped that I was pissed as a fart though I guess.
