As someone who prefers Japanese developers almost exclusively, you would think my answer would be MS. However, Sony's first party is carried so much by games from their western teams that, despite being a Japanese company, they very rarely satisfy my gaming needs.
I've always thought that Nintendo and MS could co-exist much more peacefully together. That being said, a return to the time when NEC, Sega and Nintendo were the big 3 would be the most ideal for me, personally.
