Best models to separate movies/animes?

[JestAK]

Even if I have 6 channel there is still important effects on channel with actor's dubbing.

Which models and settings will manage separation voices from sfx and background music the best with minimum artifacts?
If you experienced movie or anime separation, can you share your results?

I'm trying to figure this out myself as well. I feel like this would be a common use. I'll continue experimentation.
