That looks like the best one but the carbon credit seems kinda good too, if you're into going bigger jumps maybe. I don't know what the flex pattern of those are like but I know the Skate Banana is stiffer in the ends and softer in the middel. They didn't want the nose to bend up too much when in powder or something like that. But I imagine a good park board would be just the opposite, like soft in the ends so butter styling manuevers are easier. From my understanding, this would theorectically make it more forgiving as well, correct me if I'm wrong.
i don't consider Gnu CC a pure park board. It is more of an all terrain freestyle
