What the models actually said.
The ranking is the answer; these are the words behind it. Every quote is from a recorded model answer — follow the category to read it whole.
Rocket.Chat
Rocket.Chat — best for sovereign communications plus customer-facing omnichannel messaging: Choose it when you need self-hosting or air-gapping *and* want to bring external conversations such as web chat, SMS, WhatsApp, or customer-support workflows into the same platform.
ChatGPT
Slack
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
Where the models split.
Across the 1 category Rocket.Chat and Slack both appear in, the models never break ranks: in each one, the same brand leads on ChatGPT, Claude, Gemini, and Perplexity alike.
No model runs against the grain here: each of the four ranks Slack ahead at least as often as not, with Claude the most lopsided.
