Pick Gemini 3 Pro if you want the stronger benchmark profile. Nemotron 3 Nano Omni 30B A3B only becomes the better choice if you want the cheaper token bill or you want the stronger reasoning-first profile.

Confidence note. This is a partial-evidence comparison with 14 shared benchmark results across 6 evidence categories; 1 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.

Why this result

Gemini 3 Pro is clearly ahead on the BenchAlign aggregate, 66.85 to 43.32. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Gemini 3 Pro's sharpest advantage is in multimodal & grounded, where it averages 81.1 against 76.3. The single biggest benchmark swing on the page is CharXiv, 81.4% to 76.3%.

Gemini 3 Pro is also the more expensive model on tokens at $2.00 input / $12.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Nemotron 3 Nano Omni 30B A3B. That is roughly Infinityx on output cost alone. Nemotron 3 Nano Omni 30B A3B is the reasoning model in the pair, while Gemini 3 Pro 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. Gemini 3 Pro gives you the larger context window at 2M, compared with 256K for Nemotron 3 Nano Omni 30B A3B.
