In reailty, as long as the comparison criteria is fair, then the comparison is fair. Many manufacturers make up their own test criteria. Like testing a 46 2 stroke, and using a 9x6 prop. Sure, it will turn huge rpm with good horsepower, but reality is that aerobatics calls for a larger diameter, and racing calls for more pitch. So the horsepower numbers are worthless. I wish manufacturers would just say, 'We turned this prop at this rpm on this fuel.' Forget the horsepower all together. My Rossi 53 is rated at 2.2 horses and so is my YS 91. Does anyone really think the Rossi is a match for the YS? Not unless you're racing with a 9x9 prop. As for static thrust, as long as the data is entered into the same formula, then it's fair as well, but I would like to point out that that's not a "real" number either. It's a good "comparative" number, however.

Does anyone currently own both of these? Give them a fair run. Same prop, same fuel, and same day.

I'd bet a buck that the Moki will turn better anywhere in the 18 to 22 inch prop range.
