Why this result
Claude Sonnet 4.6 is clearly ahead on the BenchAlign aggregate, 64.4 to 50.44. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Claude Sonnet 4.6's sharpest advantage is in mathematics, where it averages 26.4 against 4.1. The single biggest benchmark swing on the page is FrontierMath v2 (Tiers 1-3), 32.400% to 5.517%. GPT-4.1 does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.
Claude Sonnet 4.6 is also the more expensive model on tokens at $3.00 input / $15.00 output per 1M tokens, versus $2.00 input / $8.00 output per 1M tokens for GPT-4.1. GPT-4.1 gives you the larger context window at 1M, compared with 200K for Claude Sonnet 4.6.
