I genuinely love both with a preference for Japanese games. For me Kojima/Miyazaki/Ueda/Sakaguchi are gaming's Mt. Rushmore and I absolutely adore the Capcoms & Platinums of the world, as well as old school Squaresoft and Konami.
That said I need my Eurojank, WRPGs, Immersive Sims, and Sandbox games from Western devs. They are vital to my gaming happiness and make up some of my highest highs.
This gen out of my Top 10, six games are Japanese (Bloodborne,BOTW, MGSV, Last Guardian, DkS3, DMC5) and four are Western (RDR2, Prey, Witcher 3, NMS) so pretty even.
