Sale& Purchase of ships

I follow a shipping blog Splash 24/7 where they have a section on S&P of ships. The ships are described as aframax bulkers, VLCCs or whatever, they always announce the year and the country of build -usually China, Japan or S Korea .In terms of quality build I assume the order is Japan, Korea and China which I assume is reflected in the sale price. I wonder if any of you have sailed on Chinese built vessels and can compare them with either Japanese or Korean vessels from a quality or equipment point of view - is there a vast difference?
