Zendesk leads the agency multi-client question with the highest score and broadest model agreement, but Freshdesk stays close enough to keep the slot genuinely competitive.
Zendesk appears in 83% of answers at an average position of 2, and all three AI models recommend it, making it the clearest consensus pick. Freshdesk matches that average position and shows up in 75% of answers, with ChatGPT and Gemini each citing it four times. The reason both top names dominate is the same: the answers repeatedly flag multi-brand architecture and unified agent workspaces as the decisive criteria for agency use, and those two platforms are consistently described as strongest there. Front is the outlier worth noting: Perplexity cites it four times against Gemini's one, suggesting it resonates more with web-sourced agency-specific content than with the broader training signal.

Slot score is position-weighted, 0 to 100: being recommended first counts far more than a trailing mention. "Appears in" is the share of answers naming the brand at all.
The main measurement above is the assistants' real answers with live web access. These rows show the same question on other surfaces: the models' bare memory, and Google's own AI search experiences.
ChatGPT, Perplexity, and Gemini each answered this question in two phrasings, several times each, with live web access and citations: the closest API-reachable version of the real assistant experience (no personalization or account memory, which no vendor can provide). Model-memory answers (no web) are measured separately and shown above as a comparison surface. A brand counts once per answer that recommends it. The exact questions:
