Just adding my two cents and being that's about all it's worth...
When I bought my Supra SA I was replacing my Moomba LSV, so already in the SC family. I seriously looked at a MB F22 Tomcat. I had an open deal on both sides, a 2015 MB or a 2013 Supra. Although the Supra was older it was still over 6k more than the MB.
There was not water available to lake test as I bought in December, so was purely going on videos, recommendations and people like this on forums. The MB is a very nice boat, they are doing some things other boat builders are not, the hull shape and surf wave looks a lot better out of the box than what I have seen with SC. In 2015 there were some issues that have been addressed with 2017 models. MB is a smaller builder than SC, but they have been around for quite a while, Mike seems very easy going and am assuming a good leader in his company. MB does not sponsor major events like SC does.
SC and Supra, I know the Craz is not a Supra. I ultimately chose the Supra because the fit and finish seemed better, the use of interior space made the SA seem bigger even though both boats were 22. The Supra Vision system as well as switches was a huge selling point. For the wife, the power adjustable and heated drivers seat along with the heater were key points.
Bottom line, the deal I got on the Supra was in my opinion better than the MB. I know I can sell my SA today for more than I paid for it, I am not sure MB will hold value as well?
With all that, my brother is looking to get a wake boat, specifically a surf boat. He is looking at MB, Axis, Supra, Moomba, Malibu etc... he has found a 16 left over Supreme to consider. INHO all things considered, spend time in each and water test them and decide from there.
