Pick GPT-5.5 Pro if you want the stronger benchmark profile. Holo3-35B-A3B only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
GPT-5.5 Pro is clearly ahead on the provisional aggregate, 100 to 78. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
GPT-5.5 Pro's sharpest advantage is in agentic, where it averages 90.1 against 77.8.
GPT-5.5 Pro is the reasoning model in the pair, while Holo3-35B-A3B 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. GPT-5.5 Pro gives you the larger context window at 1M, compared with 64K for Holo3-35B-A3B.
GPT-5.5 Pro is ahead on BenchLM's provisional leaderboard, 100 to 78.
GPT-5.5 Pro has the edge for agentic tasks in this comparison, averaging 90.1 versus 77.8. Holo3-35B-A3B stays close enough that the answer can still flip depending on your workload.
