The charts don't make this particularly clear, but the text summary mentions "Windows is stronger in terms of 1% percentile frame times.".

It's still open to interpretation what exactly they are measuring with their frame timings, e.g. is Windows consistently generating frames within 10.6ms but Nobora is up to 9% less performant then that, sometimes 11.6ms? Although this only seems to be for the 1% lows. I don't think it's a particularly insightful metric in this particular benchmark.
