Brighton. Better team, put up with more than United despite what the green and gold brigade would have you believe (limited budget, in division 4 within living memory, players and managers regularly poached by other clubs).
That said, if United won a single trophy for the biggest glory hunting fans, most rats in a stadium, best dodging of a drugs test, worst treatment of ex players, highest gate receipts generated from a tragedy, or even the most rancid meat fed to school kids by a director, I'd stil begrudge them for it. They can f off until they realise winning is not their right, and then they can f off some more.
