Pick Muse Spark 1.1 if you want the stronger benchmark profile. Claude Sonnet 4.6 only becomes the better choice if coding is the priority or you would rather avoid the extra latency and token burn of a reasoning model.
Muse Spark 1.1 finishes one point ahead on BenchLM's provisional leaderboard, 78 to 77. That is enough to call, but not enough to treat as a blowout. This matchup comes down to a few meaningful edges rather than one model dominating the board.
Muse Spark 1.1's sharpest advantage is in agentic, where it averages 80.4 against 65.2. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 59.1% to 80%. Claude Sonnet 4.6 does hit back in coding, so the answer changes if that is the part of the workload you care about most.
Muse Spark 1.1 is the reasoning model in the pair, while Claude Sonnet 4.6 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. Muse Spark 1.1 gives you the larger context window at 1M, compared with 200K for Claude Sonnet 4.6.
