Of those two I'd get the Mapex if only because dual chains. But I'd also interest you in the PDP Concept (DW's budget brand):

I have this one in single and it's an amazing pedal for the price, it feels just like one of the big boys. Fast and easy to control but still with some weight to it if you want.
