Born2fly3d,
I think these are two radically different flying airplanes. The Capiche appears to have a strong pattern heritage with big control surfaces, and would most likely do better in pattern style aerobatics, and be 3d capable.

The Su-Do on the other hand was born as a pure 3D plane. It will not compete with the capiche in the large smooth pattern style aerobatics, but for the really wild & crazy 3D stuff, the su-do-kohi will most likely eat the capiche's lunch.

I think they are really two different airplanes that shouldn’t be compared. You need to decide what you are looking for and be willing to live with its advantages and shortcomings.
