It would doubtless be easier to sharpen without the serrations. You can do the same thing with any plain edge blade by sharpening on one side only until the edge bevel is gone from the back side. Like any other chisel grind, I suppose it is okay, as long as you like to cut in a circle. Personally, I hate chisel grinds, and I'm not too fond of serrations for the same reason - I don't need to cut circles very often.
