Why this result

Kimi K2.6 is clearly ahead on the provisional aggregate, 74 to 61. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Kimi K2.6's sharpest advantage is in coding, where it averages 72.6 against 41.6. The single biggest benchmark swing on the page is HLE, 26.5% to 34.7%. Gemma 4 31B does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.
