Only you can really judge if its worth it for you.

You can get decent results if you use ffdshows high-quality RGB conversion instead of letting your renderer deal with it, and the quality difference to madVR won't be that obvious anymore.
So if you really want to use the GUI, for a minimal quality loss i would setup something like LAV CUVID for decoding and deinterlacing, then ffdshow as a post-processor with HQ RGB conversion.

Its too bad that there are so few players with a nice 10ft GUI that support madVR.
