Yes, I realise that it is not plotted with the rest of the pumps, and for good reason. If it were, it's head capacity would fall just under that of the MCP600, and its maximum flow rate would run off of the plot. Keep in mind that this pump consumes 50W, compared to the 28W of the 1250 (which is still not a particularly great choice for watercooling incidentally), and that you will be running the pump in the flattest region of its performance curve (meaning that a small change in system restriction will have a large impact on the flowrate). While you may well achieve a slightly better flow rate with the 1260, I don't personally believe that the extra size or power consumption of this pump is worth the gain.
