The Mojo will be the lighter boat of the 3 and will likely require more ballast to put out a big wave, unless you have a large crew onboard. I’ve never surfed behind a G23 or an X23 but I’d say the G will have the better wave out of the box of the 3 boats you’re looking into. It has a steep shape and lip that some people like and others don’t like. I’d be sure to surf demo all of them. A Supra would be a more comparable wave to the Nautique or MasterCraft boats than the Moomba will. That being said you can make a Moomba throw a big meaty wave with the right ballast setup.

If buying new your dealer will be nearly as important besides the brand of boat. You could buy a badass boat but have a crappy dealer ruin the ownership experience. So I would not only shop the boats but also shop the dealerships. That sometimes will matter more than surf performance.
