Not sure what kind of conclusion you're trying to reach there. Out of the two games I played, DMC was the best one. Never tried the other two in depth (in 3's case, at all) so i'm not sure if they're any better. I heard 3 was the best in the series based on reviews, but I rather try it someday and make up my own mind about it.
I don't know why HR is being mentioned but I heard that same type of argument that you can play the game on youtube since its essentially a movie. But its not Plumbers Who Don't Wear Ties that has only three possible outcomes you can sift through in 2 minutes by only clicking. And last I checked, not every choice is on YT. Plus the interactivity aspect, no matter how limited, gets you in the game through its little QTE moments and mini-games of sorts. But that's a different thing altogether from DMC.
