Cuvid only has drawbacks over D3D11VA:
It wastes power by preventing downclocking of the card, is less maintained by Nvidia regarding bugs and there is only a copyback mode available with LAV Filters + madVR, which causes overhead on both CPU, GPU and RAM.
Only current advantage for Cuda would be deinterlacing, which is not yet implemented into madVR with D3D11VA. I think it's also just a myth that Cuda deinterlacing would be better in terms of quality. It's not better than D3D11VA and still inferior to YADIF.
