Theres a big difference in focal length of 1000mm between the 2 scopes, and that makes a huge difference when conditions are poor. You just magnify more seeing error with the longer FL.
As shown with the sigle sub of the bug nebula, a huge difference during different nights of seeing.
During that night i got just over 3 FWHM on focusing.
Star dancing was near non excistent.
Speaking about the 12.5" CDK, it is a popular scope, but i think with these new cheaper RC's, its going to be a real big competition.
