The ranked list
Slack holds the consensus #1 at a score of 75, with Claude and Gemini and Perplexity placing it first outright.
For a typical company buying today, I would choose Slack unless the company is already deeply standardized on Microsoft 365; then I would choose Teams.
ChatGPT, this closeSlack – The most polished and widely adopted team chat tool, with the richest third-party integration ecosystem (2,000+ apps) and excellent search/workflow automation, making it the default recommendation for most companies.
Claude, this closeMicrosoft Teams ranks #2 on consensus with a score of 64, scoring best on ChatGPT (#1).
Microsoft Teams — best for Microsoft 365 organizations: Choose it when Outlook, SharePoint/OneDrive, Office, Entra, and Microsoft compliance administration are already your company standard, because its chat, channels, files, meetings, and collaboration are tightly bound to that environment.

Claude, this closeGoogle Chat ranks #3 on consensus with a score of 54, scoring best on ChatGPT (#1).
Google Chat — best for Google Workspace organizations: It is the sensible low-friction answer for companies living in Gmail, Drive, Docs, Calendar, and Meet, since Spaces are built around collaborating on Workspace projects rather than adding another major platform.
ChatGPT, this closeGoogle Chat (Google Workspace) – A strong pick for Google Workspace shops, offering seamless integration with Gmail, Docs, and Meet, though its feature set is slightly less mature than Slack's.
Claude, this closeDiscord ranks #4 on consensus with a score of 32, scoring best on ChatGPT (#1).
The models disagree about it more than most: #1 on ChatGPT but #10 on Perplexity, a spread of 9.
Discord — only for informal, community-like, or developer-adjacent teams: Its real-time voice and channel experience can be excellent for highly social groups, but I would not make it the primary company system of record where formal governance, compliance, external collaboration, and business-process integrations matt…
ChatGPT, this closeDiscord – Increasingly popular with startups, remote/dev teams, and community-driven companies for its low-cost, voice-channel-friendly, and highly customizable environment, though it lacks some enterprise governance features.

How are these rankings measured?
We ask each model the same buying questions on every run (1,480 queries this period), record the full answers, and score each named brand 0-100 by how early and how consistently it appears. Every question runs through the official model APIs, with web search on, not through the consumer chat apps, so nothing is personalized to a user. Each model is scored independently; the consensus blends all 4.
Do the AI models agree with each other?
At the top, yes. Every model crowns the same #1 at the latest close. Further down the board they diverge, which is why each brand carries a spread figure: the gap between its best and worst model rank.
