HubSpot CRM came up in 113 of 150 answers about CRM, Microsoft Dynamics 365 in 36. That is 77 answers apart on one capture date. There was no question where Microsoft Dynamics 365 was named and HubSpot CRM was not. All five engines named Microsoft Dynamics 365 at least once.
HubSpot CRM is the most named checked vendor in CRM in this release, so every other vendor in the category is compared with it.
One capture on 22 September 2026, ten fixed questions, three runs per engine. Not a ranking, and an engine can answer differently on a refresh.
Each engine's count over its valid answers to all ten questions.

Measured head to head
No question in this release asked the engines to choose between Microsoft Dynamics 365 and HubSpot CRM; the counts above come from the ten buyer questions.
What the engines said about each
Microsoft Dynamics 365 Sales, strong if your team already lives in Microsoft 365 and needs configurable processes with tight Microsoft integration.
My default recommendation is HubSpot Sales Hub Professional, assuming you want to standardize a growing B2B sales process rather than build a heavily customized CRM.
One sentence per engine at most, chosen by a fixed rule: the first full sentence naming a checked vendor, read in run order. Every answer in full: DOI 10.5281/zenodo.22907695.
What to do with this
Microsoft Dynamics 365 claims its record, free, and runs the free check on its own name. The widest gap is on “What is the best CRM for a growing B2B sales team?”: that is the question to fix with Answer Repair, $490.
