The thing is though, is there any reason to believe the PLA would be in a much different shape? The last wars the Chinese fought in were decades ago, and the performance was pretty poor. So we don't have any real world idea of how that army would perform - it could suffer from poor morale, stupid tactics, lack of coordination, no logistics, or it could be superbly trained with great equipment.
