Except it is. The LoS series has thus far been the ONLY Western Castlevania Konami has published. You can't possibly make that statement that the japanese make better castlevanias when they have had many different games made by different people, and the west only has one game series made by one outside company's dev teams, and the same director.
Once the West has made a few more CV games, by different developers, THEN we can talk about west vs JP CV.
It's like saying Johnny is better at drawing than James, when he is an established artist with tons of works under his belt, and James has only made one set of works so far.
OK, when the west make more CV games we'll see. I personally expect they return to Japan for good.
But the point that only japanese get it right, if only japanese and MS did CV games so far, remains true.
Japanese get what a CV game needs, MS (in my opinion) don't.
Perhaps, if in a near future WayForward give us our so desired CV with CV signature music, the west will have a few more points and many of us will have more faith on future western projects.
But I still prefer that they return to Japan, even if IGA, Michiru Yamane and Ayami Kojima are not involved anymore.
Give me another game like The Adventure: Rebirth and I'm happy
