Pick Gemini 3 Pro Deep Think if you want the stronger benchmark profile. Qwen3.5-27B only becomes the better choice if coding is the priority.
Gemini 3 Pro Deep Think is clearly ahead on the aggregate, 80 to 71. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Gemini 3 Pro Deep Think's sharpest advantage is in agentic, where it averages 78.1 against 51.6. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 77% to 41.6%. Qwen3.5-27B does hit back in coding, so the answer changes if that is the part of the workload you care about most.
Gemini 3 Pro Deep Think gives you the larger context window at 2M, compared with 262K for Qwen3.5-27B.
BenchLM keeps the benchmark table and the operator tradeoffs on the same page so a better score does not hide a materially slower, pricier, or smaller-context model.
Runtime metrics show N/A when BenchLM does not have a sourced snapshot for that exact model. The scoring rules and freshness policy are documented on the methodology page.
