2012 Axis A20 vs 2011 MB F21

I have ridden behind both wakes and love them both. We mainly wakeboard but occasionally surf. Which boat will hold it's value more? The Axis is loaded with everything possible basically the vandal. . The MB has everything including tower speakers and amps as does the Axis. The Axis has a tricked out trailer. The Axis is about $6000 more. I am so confused. Any opinions on which one and why would really be helpful. They are both beautiful. Help! I know MB has changes on the 2012 but to me are not a big deal.
