@keene I like it, but I think it needs a subtle marker showing the halfway point on the bars
Because otherwise it's not immediately obvious which player has more or less than 50%
I would suggest putting markers at the halfway point, and also 5/9 of the way and 4/9 of the way between the two extremes (because those marks correspond to one player having 20% more than the other player). Then it would be easier to see who has more and who has less.
People shouldn't have to read the numbers at the edge of the bars or use their eyes to guess at which bar is bigger. Come colors "pop" more than other colors, so it might be if you're bright pink at 48% to 52%, it looks like your bar is bigger than your opponent's. If there's a subtle mark at the 50% point, that takes away the ambiguity.
