Eh, we've all played this game, we all know what the score is.
A fast brick gets frustrating because of the difficulty following things around to shoot them, a turny kite gets frustrating when you can't catch anything or get cornered and bnz'ed to death by 5 of 'em.
Real life, I want the fast plane so I can run to live when it gets too hot, as far as which is more desirable in a game however, I say 6 of one, half-dozen of the other.
