I think the 30HP Cyclonic is 810cc so it is almost 100cc larger than the 726cc Kawasaki. Its hard to compare HP to HP since Briggs is using a different rating method than Kawasaki. I would look at cc and torque if available to get a decent comparison.
When you get a 30HP Cyclonic from Briggs it has a 1 year commercial warranty vs the 3 year from Kawasaki. However on a Ferris machine I believe they are giving you 2 year commercial use warranty with that engine.
For home use I would probably take the Cyclonic. Or even light commercial use. But if you are going to be using it 40+ hours a week I would step up to something else. Or if you just want the better engine for home use to have bragging rights.
The net hp for the Briggs must be kept to within 15% of its listed gross, meaning it will be in no less than a 25.5 hp range based on their rating system. The Kawasaki is rated to within 2% of it listed gross meaning it be within 1/2 hp of its rated 24. The Briggs will probably be more powerful, but may not hold up as well as the Kawasaki.
