I think there's no need to double column names and to mark lines with colored tabs. Aligned information creates visual lines by itself. Usually the less visual elements you use, the better. Also, numbers could be like 80% white instead of 100 for better representation - it's easier to percept less contrasted data.
I would prefer left Leaderbord as it is easier on the eyes while right one gives me that "boom flash" of colours strain to your eyes. Just add extras from Right one to layout of the Left image and it would be very nice. Anyway I am old fashion and like things simpler with less decorations "more raw" stuff.
