When I hear talk about the Xbox One not having enough quality it usually means that it does not have the same quality when it comes to third person action adventure games and not doing the in thing right now where Japanese publishers and developers have been going hard at remasters. It also takes away from the fact that like Sony who have tried with Driveclub and GT Sport in racing, Microsoft have attempted having some third person adventure games that did not pan out like ReCore, Ryse: Son of Rome, Quantum Break.
It is a case of two consoles having strengths in different areas.
