I think you are asking the wrong questions. There is so much more to a skid steer than the engine. In fact most breakdowns you will encounter in owning one are not due the engine. Maybe bolt on accessories on the engine but not the engine itself. They are all pretty good.
Whatever brand you buy make sure you have a good dealer close by and that they are a full service dealer with lots of parts in stock. Nothing against mustang gehl Tak etc they make good machines but they don't have near the dealer network of Deere cat bobcat. I really wanted to try a Tak when I bought my Deere a couple months ago but the closest dealer is 130 miles away and they are not even a full service dealer.
If you are getting the biggest skid steers hauling them is a concern. My Deere weighs over 11,000lbs. Couple that with a trailer that can handle that much weight and you are most likely in CDL territory and will want a dually to tow it. They will very likely overload a 14k trailer which means tandem duals or triple axle.
