Pick Qwen3.6 Plus if you want the stronger benchmark profile. GPT-5.5 Pro only becomes the better choice if agentic is the priority.
Confidence note. This is a partial-evidence comparison with 4 shared benchmark results across 3 evidence categories; 3 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.
Why this result
Qwen3.6 Plus has the cleaner BenchAlign overall profile here, landing at 65.2 versus 63.69. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
Qwen3.6 Plus's sharpest advantage is in mathematics, where it averages 60.5 against 48.1. The single biggest benchmark swing on the page is FrontierMath v2 (Tier 4), 39.600% to 8.333%. GPT-5.5 Pro does hit back in agentic, so the answer changes if that is the part of the workload you care about most.
