I own a NO4 and my brother has a sportered 4. I have played with a few NO1 MKIIIs in the stores but to me they just seem like a bulkier design that is more front heavy. I'm not knocking the design and if I could find a decent one at a decent price I would grab it in a heart beat but I do believe that the NO4 replaced the NO1 with good reason.
