I guess it would have to be quicker, if you have it set for a particular size cog and always grab that one. My style (which I don't think I've ever seen elsewhere) is pretty easy to use though, and would be right up there with a bit of practice.
A bit of a shake to throw the loop around the teeth, take up the slack, and bam.
