Hi i think the arcade has a more "solid" feel due to the steel frame, and I'm more used to that due to 20+ years on bmx bikes. So for the street park I find I trust i more...the arcade bunny hops really well, where as the hex has a "bigger" feel to it which i dont like. This "bigger" feel in turn makes it better for static moves and rolling over stuff. The fourplay is a bread of its own. Fun and stable but not as lively as the others. All are killer bikes, so really hard to give recommendations. ..but you know some days you wear sandals, some day boots..
