I doubt performance can be a reason to prefer other platform than VVVV, especially in cases of single installation. The development time spent with optimizing would cost much more than slightly better hardware.
oF and Cinder are free even for commercial projects, again, this is advantage only if you are really solid with C++ and you code really fast and/or you want to use the app in high number of instances. Or the app is so easy, that you can code it in less than 500EUR of you time.
oF is multiplatform, with some projects you might (need to) pick some small factor platform like Raspberry Pi, where Windows and VVVV will not run. Also, some clients like museum tend to avoid PC/Win as they fear it might be less reliable in a long term.
Single interactive installation with Kinect is most likely a job for VVVV.
