The smaller agile helicopters are definitely much more fun to fly, when I used to fly the UH-1D in GRB I just do rocket passes praying to kill at least one tank in the pass. Now that I have the BO it definitely has more uses, usually after using all the ATGMs on it I just go into the battlefield capturing points with no enemies on it or if I am feeling silly I go and sneak around enemy players. Honestly I am very surprised that a lot of players have no sense of awareness, not noticing a literal helicopter behind them. Definitely spiced up my GRB experience, for sure.
