Pick Sakana Fugu if you want the stronger benchmark profile. Inkling 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.

Confidence note. This is a partial-evidence comparison with 7 shared benchmark results across 4 evidence categories; 4 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.

Why this result

Sakana Fugu is clearly ahead on the provisional aggregate, 76 to 69. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Sakana Fugu's sharpest advantage is in knowledge, where it averages 95.5 against 51.7. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 63.8% to 80.2%. Inkling does hit back in coding, so the answer changes if that is the part of the workload you care about most.

Sakana Fugu is the reasoning model in the pair, while Inkling 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.
