You assume too much. You and I have no idea what makes Cubase sensitive to certain issues. There are tremendous number of implementation details that are entirely different between the various DAWs. You can’t confuse Cubase and Reason. They simply are not comparable environments. And, I have a few friends who have given up on Ableton because of the constant crashing.
I’m not defending Cubase as much as saying your assumption is completely without basis.
