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.
HubSpot Service Hub
HubSpot Service Hub — A strong choice if HubSpot is already your CRM and marketing system, since its help desk gives agents CRM-native customer context, automation, AI assistance, and connected-channel support without another customer-data silo.
ChatGPT
Zendesk
Zendesk — My default recommendation for a growing or complex support organization because it is the most complete general-purpose platform for high-volume omnichannel ticketing, skill/SLA-aware routing, workflows, reporting, knowledge base, and AI—though it can become expensive and administratively heavy.
ChatGPT
HubSpot Service Hub
HubSpot Service Hub — The best choice for companies already running HubSpot CRM, because website chats can be routed to sales or service while preserving the lead and customer context in the same system.

Zendesk
Zendesk — Choose this over Intercom when you need a more mature, highly structured omnichannel support operation with serious ticketing, routing, reporting, and room to scale across many teams.
